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 ?

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.

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.

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

The real oddball would have been the ME-9500. Long conventional with the 637 gas V-8 in it. Brochures show that model available in '66-'67, wonder how many they built. I have seen JE-9500 short noses with the 637.

Bob,

The '71 9500 I used to drive had a 637 in it. It also had a 10-Speed Road Ranger in it. To this day, since we got the truck in the spring of '72, I have never seen, or even heard of another, with a Road Ranger trans. Just about all the 637's in J or H 9500's I have seen (online only) through the recent years were in Fire Trucks, but every one was a 5-Speed, 2-Speed Rear.

Glad to learn something new. I never knew my old truck was a "JE". Also never knew they made an "ME".

My "JE" had 12 Fronts and 34 Rears (20 Ft Flatbed Dump). I'm going to say that the RR was a 610.

The 637 didn't have much Torque and you had to do a lot of Shifting, which I didn't mind, lol, but was a real good all around truck that hauled some interesting loads.

Most all of the 637's I have ever seen were in fire apparatus as well! Many were in steel tilts, the rest in H/J's. I have never driven a 637, but those I know that have all said the same thing- not a lot of torque at low r.p.m.'s, had to gun them to get any power out of them. Not like the V-6's, isn't that strange?

[C10 - C90 Bill]

It is strange as we also had a 478 V-6 in a '62 6500. The 478 had a ton of Torque, and they both looked alike. The 637 looked just like a 478 with 2 extra cylinders "welded" on.

That always puzzled me until one day someone explained that even though they looked the same, they were very different inside.

Pretty much like a Detroit. You had to Shift it like a Detroit as well, lol.

[C10 - C90 Bill]

Bob,

We may have asked you this already, but do you remember any 12V-71's in an MH-9500 Long Nose?

Some say they were available and some say they weren't, but it seems that somehow, some were out there.

I really don't think any M's left Pontiac with 12V-71's in them. Since a 6-71 was used in the MI-9500, a 12V should fit considering the 12 and inline 6 are the same length. The only fit issue I can see would be the air compressor which on a V engine usually is bolted to the timing case at the rear of the engine. Guess you would have to use a belt drive compressor on the front.

Another GMC 'unicorn' is the tandem axle Steel Tilt 9500 with an 8V-71 in it. Both the 6V-53 and 6V-71 were used offered in Steel Tilts as regular options, but I have been told there were some built with 8V-71's for auto haulers, notably Pacific Motor Transport on the west coast.

Not mine, but cool

[special-K]

Very interesting. Looks like that thing was one heck of a wrecker in it's day. It's day could come again!

[C10 - C90 Bill]

They are both very restorable.

The Long Nose has the indications of a '66 or '67 though.

Are you going to buy them Tim?

[special-K]

I don't know why they couldn't put a price in the listing. I hate calling just to find out if I even want to consider buying something or not. Fact is, if they were $1,000 I couldn't do it anyway.

I was thinking the same thing on the long nose being 66 or 67, then I saw them claim it's a '69 and started doubting what I thought I knew. I see the emblems and turn signals not on the front indication early model

[greywuuf]

three horns.... doesn't that indicate some special package ? or was it optional seperately ?

The triple Grovers were a regular option, but it appears they were on many of the special 9501 'Western' versions.

Not sure the year but he's about to drive up on the portable scales

[C10 - C90 Bill]

I'm not good at the older years, but I'm going to say some where around 1935.

Interesting picture.

[watahyahknow]

realy like the looks of that era trucks
theres not a lot left here out that era because of the ww2 they all gotten scrapped for the war effort

[greywuuf]

here's one for you to "put a year on" ! lol
front mounted lights ( one of each ) tilt hood chevy, no emblems and 3 different clearance lights !


oh and mounts for a single grover horn ( the horn currently resides in the cab )

[greywuuf]

just noticed the no air horn truck in post #171...... are those millitary NDT tires on the rear ? what a gawd awful beast that must have been on the road, wonder if it was a special order mining or construction truck or something?

[mrolds88]

No. They're not NDT's. Close. NDT's at least of that era have a wider tread separation. Had a truckload of them at one time.

Seen several references to "steel tilt" hoods. Can someone explain what that is?
