Re: GM Semis
 

If you're talking about the 70 series with a Brigadier type cab on post #460 dated 1-26-14, [don't make me guess next time] , it has a steel butterfly type hood. The fender opening are normal for those hoods. Only when the hoods with fiberglass tilt did they have deeper skirts in the opening on 74 and up due to the cab being raised 4" . Prior the fiberglass fender opening looked the same as this one .

This is not a "C" series, but a "J" series model.............[more heavy duty].

Re: GM Semis
 

Junkmandan3, Thank you for the reply, Sorry about making you go searching ( I had posted it in the other thread hoping you would say something about it and never thought to tell you where to look ) and yes it is a "J" model I tend to lump it together with my C-60 because people tend to know what that is and only truck guys know what a j70 is.

I knew the truck I pictured had a butterfly hood ( it is mine just waiting for the snow to clear to work a deal with the yard it is in and go bring it home ) I guess what I am confused about is what exactly ARE the side skirts you and Bill talk about, I look at the truck in post #427 ( that started that conversation) and am unclear what I am looking at ....also the raised hood... is it a taller hood and grille shell or just raised up off the frame ...I guess I am failing to "put it all together" as far as building my own "spotters guide" what year did the raised hoodline come about ? and one other little issue I am having is that on my truck the glove box tag lists the driven front axle so it came that way, but I am unsure if it would have come like it is now... budds ( or motor wheels) up front, Daytons in the back ..... did they mix an match like that ? or has mine been hacked at some point?

Re: GM Semis
 

The skirts I'm talking about are the outside edge of the fender that would contain the wheel splash[theoretically], and this seems to depend on whether it has a raised cab, which is dependent on the engine choice . Since I have GMC data books for 1966 and 1974 , I just referred to cab height dimensions for the short nose [90"bbc] like yours. They list 57.5" above the frame for 6-71 and 250 Cummins , while the top of the cab is 61.5" above the frame for the 8V71 or 290/335 cummins. I recall this dimension was critical for our DDA shop because with the stamped steel valve covers ,our mechanics would loosen the left cab mount for clearance. I believe the cast aluminum covers clear OK . You may be aware the 8V71 is tilted tothe right on the short conventional . We had a steel hauler in Cleveland called Dworkin that originally had the 113 BBC MH model, then bought the 90" BBC JH model .
The hoods are the same, except how they're mounted. From what I've seen[with fiberglass hood], with low cab the hood is hung on a cross tube bolted to the frame, but on the high cab the hood hinges are bolted to the bumper.
Budd front and cast spoke rear was a fad from the 70s, but usually the 4 wheel drive setup in that era was an aftermarket installed unit and they might put on what was most readily available or popular. Howe-Coleman in Troy New York specialized in those modifications and in the Tulsa,OK. area there was another vendor .

Re: GM Semis
 

As far as we can figure, the Raised-Up Cab with the Wider Fender Skirts started in either '73 or '74. Your Truck is consider a "Low Cab" even though you have it "sky high" with that Front Drive Axel on it !!

Also want to add that the Raised-Up Cab was on the C-90's and 9500's only. The C-70 and the 7500 Series trucks were all "Low Cabs", on the earlier ones anyway. The White Dump that we were talking about earlier is a puzzle to whether if it is original or not.

Re: GM Semis
 

Thank you both, I see the how the two trucks differ now, I can always learn something here if I pay attention.

Re: GM Semis
 

I hope this hasn't been posted already. Pardon me if it has. I thought this '31 GMC was pretty awesome. I am going to ask my dad if he has any pics from logging in the '60s, '70s, and '80s and, hopefully, I'll get some pics with history up. Anyway, I thought this was cool.

Nice, Probably has one huge buick engine in there.^^^

Re: GM Semis
 

Now that's a rig! Gotta figure what all those little jars of baby food weigh. That's a long hood and big rubber

Re: GM Semis
 

Picture # 288 on page 12 is how Fred Craig's black MH looked when he bought it . That picture was taken at the ATHs convention in Greensboro in '97.

It is pretty neat. Reminds me of the "Duel" Tanker.

Re: GM Semis
 

That truck is a fine example of an MH. One of the nicest I've ever seen. I actually always thought it was a factory photo.

Re: GM Semis
 

Kool it--------- reference 574----The picture of the ? with big sleeper looks like something I saw at the first Pocono Truck race in 1983. Seems then it had a regular MH hood with a big set of bull horns 4' long fastened on top of the grille, plus 2 Astro cabs siamesed together.

A better pic.

Nor my pics

Re: GM Semis
 

Pretty neat treatment of grafting the Brigadier fender pods and Topkick grille on the MH hood. If I could find pictures from 30 years ago, it probably was KW sleepers instead of Astros. Thanks for posting tat one and the many others you have . As a newby, I'm only part way through the pictures so far .

Re: GM Semis
 

Glad you liked them.

I can't be the only guy with pics?

Re: GM Semis
 

This MH with Mercury Sleeper is in Pennsylvania, [or was], as I got pictures of it at Macungie 5 years ago . It came out of the southwest in better than average condition .

Re: GM Semis
 

Nice looking truck.

Like the Chrome Package.

'73 GMC MH 9500:


Dan, Check out who posted the Video.

Re: GM Semis
 

Re: GM Semis
 

Low cab with the early Chevrolet style grille. Newer Chevy's with raised cab have the headlights in bottom of grille panel like Ashton Lewis' in previous picture .

Re: GM Semis
 

Nice looking Wrecker. Those Grilles are a puzzle to me. When I first started seeing them, especially on older wore out trucks, I first thought that someone did some changing around and put a Chevy Grille in one, but I've seen too many of them now and it seems like they were most likely factory.

Maybe it was an option if someone wanted Single 7 Inch Headlights instead of the usual Doubles? Anyway, as Dan has indicated, they were only on Low Cab 9500's.

Re: GM Semis
 

Re: GM Semis
 

Kool------Where did you ever find that picture of a double bunk Astro ? As an avid collector of GMC literature ............and trucks, I only heard about those in 2010 when a Dan ? from Deerfield, New Hampshire posted on the ATHS forum that he owned one of possibly 11 being built . If you see that forum, he posts under "Cabover Kings" and the thread started 2-1-2010. He shows some pictures of his 1983 vintage Astro that he bought as a basket case, but was also able to get the original 3406A Cat with a 9 speed transmission. Do you have a sales brochure where this picture was copied from, or was it a single advertising picture?

That thread is current on the forum with new pictures.

Re: GM Semis
 

Facebook...
Amazing the neat pics that show up.

Re: GM Semis
 

Did you have any idea they were that rare? I couldn't believe it when that thread started.
But that's kinda like the Generals with 60" sleepers . The Shroyer collection has the 1st one I've ever seen, but then 6 years ago on return from the Louisville Truck show, i happened upon a guy near Mansfield, Oh. that not only had a General with the 60" sleeper, but had a 60 series Detroit . I passed the tip on to Dave Schroyer and Robert Manley of Florida. Manley ended up with it, but ruined it's uniqueness by moving the cab back after stretching the frame, stretched the hood, and changing the sleeper back to a typical 42" Bentz. Oh well, his truck,his money............I gotta get over it !

Re: GM Semis
 

No idea it was a rare bird. Liked the paint scheme.

Re: GM Semis
 

Fine example of an earlier 9500. That truck is either a '68 or '69.

Also has that nice optional Chrome Package.

Bill

Re: GM Semis
 

Bill-----How are you determining the year by subtle clues ? I'm guessing you're looking at the front turn signals that are larger [than the common Signal Stat] with a bastardized 3 screw mounting for the lens . I have a EM 5500 that has those lenses that I couldn't identify to replace . Then the first year or so, were the turn signals all up on the cowl between door and hood ? My EM 5500 also has front parking lights mounted behind the grille . Then somewhere along the way, GM started using the plastic square signal lights with single contact bulbs for the turn signal and a marker light visable only from the side . I thought that light should have had a double contact bulb for parking light as well .

Re: GM Semis
 

Dan,

Right, the main tell-tale sign is the Directional Lights. The style of them and location. The '66 and '67 were up near the Cowl and were the more narrow "Signal Stat" type as you have indicated. The '68 and '69's were moved up front and are the Larger Round type as shown in the above picture. In 1970, they went to the Square type. There are also other smaller signs that I look for including style of the Cab Lights, Side Emblems, etc to verify the year, the best I can.

Right about the Square light as well. It is about a 3-Purpose Light. Parking, Directional (and Flashers) and a Side Light built into it.

I also remember the Parking Lights in the Grille. Thought they looked pretty cool really, but I have never paid enough attention to them to try to determine what trucks got them and which didn't. Always just thought they were an Option really.

Bill

I know where there is one like the one in post 598 sitting that looks complete with tractor and trailer. It has been there as long as I can remember. I need to stop and ask about it sometime, or at least get pictures.
