Back around a dozen years ago, I bought a model 700 fat cab , down in remote SE West Virginia . It had a small displacement "big six" engine, had been a fire truck in New Jersey, later got repurposed as a tractor with 5th wheel, air compressor for trailer brakes with an air over hydraulic master cylinder. Kind of an unsafe truck because no brakes til you got air built up, somebody took the parking brake parts and lost them .

It had the unusual cab with no center window , but had the corner windows.
I first thought somebody,[perhaps the firetruck body manufacturer], had taken a sheet of steel and blocked off the rear window . But soon a friend sent me a copy of that same ad regarding fat cab options .
All in all, it had a nice chrome grille with only 1 hole in back of cab for a heavy duty radio antenna. I was gonna repower with a 4-71N with an added turbo, but ended up selling and delivering it to Indiana, Pennsylvania .

There was one old truck I used to drive when I was 16. It was an AD, I'll guess about a '53. Believe it was a 3/4 Ton and it had a Flatbed with a pretty restricted Head Board on it. I believe it had a Small drivers side mirror and None on the passenger side. That truck had no business being on the highway, but those are the roads we took sometimes. I would always ride in the right lane to not get into any "situations" with it, but once in a while you had no choice, lol. I remember one time yelling over to my friend to hurry up and look out the right side to make sure nothing was there!! Glad I never was alone on the Interstate. Boy that truck had horrible Brakes too.

Beautiful truck.

This would be an early model, '66 or '67.

[special-K]

It sure is. Well optioned, nicely accessorized...clean and subtle, with a tri-tone scheme that goes with the body. That paint has a fleet look to it, which I think is cool.

Bill, one of these days I'll have to get you to teach me all the ins & outs of identifying the years, configurations, etc on these.

FYI, that ATHS Tri-State show is coming up next month in Winchester. I know it's still a hike, but not all that bad...if you can swing it

[C10 - C90 Bill]

Tim,

Winchester is about 4 hours away, and I'm going to make it there someday, lol. But doesn't look good again this year.

The way to identify the years is by the Directional Light locations and the Style of them. Also by some of the Emblems. Sometimes Cab Lights and it seems like the Triple Horns were only on the early models as well. But this is all if the truck is original. When things get changed around, it can really throw you off, lol.

[special-K]

I'll keep reminding you every year and the rest is up to you.. I don't doubt you would like to go.

I've seen you mention those differences but not sure what or when. I see this one is before the 69-72 style emblems and no body mounted directional signals. There's also the weights by bumper, fenders, and headlight location, right? Between you and Dan I'll get it one day. I think I need to see a thread showing examples of all the differences to study.

[C10 - C90 Bill]

The '66 and '67's have Thinner Round Directional Lights located on the sides of the Cowl. Sometimes they are hung on the Mirrors like the truck above, but I would really say that was more in '66 than '67. Also the Style and Location of the "GMC 9500" Emblem. The early ones also have the separate "Diesel" Emblem on the side at the front, also like the truck above.

In '68 and '69, the Directional Lights got moved to the Front, were still Round, but a little different Style and somewhat Thicker. I believe the Emblems then got changed to the type that we are more familiar with, moved to the side of the hood, and also the separate "Diesel" Emblem was dropped.

In '70, the Directional Lights went to Square.

As mentioned above, it seems like the Triple Horns were on the early ones only.

Now this is all for Low Hood Trucks.

The Raised Cab was out in '73 or '74 and had many visible differences.

Dan will probably know more about the Raised Cab trucks than I would. But I believe one of the reasons was to have a Larger Radiator in it.

But when I try to determine the year of a truck, I try to take all the details available into consideration, and as mentioned above, once something is changed around, it can be a challenge, lol.

The real way though, if possible, is to check and decode the VIN on it.

For a good example of a '68 or '69, check back to post #1138. It's a Chevrolet, but has a good example of the Round Directional Lights that were moved up Front. Although the Brochure says "1970" lol. They are known to be wrong. Unless they used them very early in the year, which is possible, I believe they used a '69 for the picture.

And I got the pic for the 3 horned Long hood.
Didn't even look at the ATHS card, I zoomed in. Appears to say 68

[junkmandan3]

I first saw that MH 9500 on post 1165 at the Colorado Springs convention and noted the triple horns at that time in my pictures . They were option "UO4" in the 1966 sales data book [for '67] and were listed for $125.00 at that time.

Does anybody have any data on options or frills on the MH or MI 9501 versus MH or MI 9500 . Supposedly was more deluxe, per rumor, but how ?

Dan,

I found something on it that Bob B. wrote on Page 33 in this thread:

"Went back and looked closely at this truck. I think it might be an MH-9501, not the standard 9500. The 9501 was a special lightweight 'western' style long conventional (think Peterbilt 359). The 9501's usually came with Alcoa wheels, lot of other aluminum parts like fuel tanks, ect., and a 318 horse 8V-71/Roadranger. One other feature the 9501's often had was a 3 trumpet Grover air horn. Take a close look at the horn on this one."

Unfortunately the picture that Kool posted is now gone (at least I can't see it now).

I have a '67 9500 series service manual, and it shows some different drivetrain and axle options for the 9501's, but no information of trim and accessories.

Thanks for all that info. I'll have to save that.
