GMC 3500 longhorn stepside - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1970GMC3500Longhorn · 09-26-2019, 09:43 AM

Im looking for some more information on my latest project. Is there any good sources of information on what the original purpose could be for? Or any production numbers available on how many longhorn stepside’s with a 9’ box were built? Thanks

That my friend is a thing of beauty! I also am interested in production numbers of this truck.

Willys_MB · 09-26-2019, 10:26 AM

Wow, that's an amazing find. It looks to be in pretty good shape! I'd love to see more pictures of it and the interior as well.

I don't have access to production numbers, but I remember reading some story about a fire destroying most of the GMC records. The experts will probably chime in soon.

Welcome to the board!

THose hub caps look older???

Is glove box decal still intact???

Way cool, thanks for sharing!!!

1970GMC3500Longhorn · 09-26-2019, 11:25 AM

The rims are 3 piece split rims, I’m not sure what they came off of. But the hub caps have Chevy emblems

1970GMC3500Longhorn · 09-26-2019, 11:27 AM

The truck is in good shape overall but it will need a lot of loving

68panelman · 09-26-2019, 12:00 PM

Welcome to the board! Love 9 foot stepsides!. It's true, you won't get any production numbers, just guess-abouts. Hubcaps look 65-66.
These were the true workhorse no nonsense truck. Probably has 4:56 gears..or worse 5:17's!. I owned a 69 GMC K2500 V6 8' stepside, same interior color as yours too.

Warrens69GMC · 09-26-2019, 12:06 PM

wow!

**Chevyland** · 09-26-2019, 02:25 PM

Nice Truck
And quite rare

I believe that is a c30 9’ Stepside
Not to be confused with a Longhorn
Which would be an 8-1/2’ fleetside bed

Nonetheless, it is really cool

I don’t think this book has the GMC production #s
But you can see very few Chevys in that configuration
We’re built
I’m sure GMC #s were even fewer

In the spid picture, I can’t make out Wheelbase length
Are you able to see what it is ?

I know Longhorns were 133
And c30 dually trucks were either 133 or 157

Never even thought about what c30 long steps would be
I’m sure somebody can chime in on that

68panelman · 09-26-2019, 02:36 PM

Wheelbase on the 9' step would be the same as the longhorn at 133"

1970GMC3500Longhorn · 09-26-2019, 03:20 PM

Thanks for the information guys! Any idea what rims would have came on the truck originally? Also what kind of bumper it would have had on the rear?

**lolife99** · 09-26-2019, 03:57 PM

Very cool truck.
I’ve only seen one c30 stepside with a 9’ bed.

**Chevyland** · 09-26-2019, 04:38 PM

And I’m guessing it had split rims on it
But if it had caps
I’m thinking they were white
Because it was not a high trim truck

71gmcC15 · 09-26-2019, 04:39 PM

Its a gmc so it's a fender side. Haha beat you to it. You know how your are haha

**Chevyland** · 09-26-2019, 05:14 PM

If you want correct ones
Here they are
They are on ebay right now
And
That is only for 2

72c20customcamper · 09-26-2019, 05:22 PM

I think a 30 would have had 17 three piece rims . My 20 has heavy duty front and rear springs with 17"

1970GMC3500Longhorn · 09-26-2019, 05:43 PM

I currently have 7.50x17 3 piece Chevy rims. 7 of them with 4 Chevy center caps. Does anybody need them? I don’t want to use them if they are for an older model. Plus the tires are pretty expensive

Thank you! I wasn’t sure if it was a Longhorn or not. But it does have 133” wheelbase

Rear Bumpers were not required on these trucks so you could have factory ones like my 68 or a plethora of after market ones.

factorystock · 09-26-2019, 11:05 PM

Judging by the hubcaps, the wheels are off a '64-'66 C 20 or C30, however, the 17" 3 piece wheels were used up to '68. '69 and newer 20's or 30's generally came with 16' 2 piece wheels or 16.5" wheels with bumps for hubcap retention. Most run the newer and plentiful 16" 1 piece that came out in the mid 70's and used up to '91. The white 12" GMC hubcaps posted are the correct style for your '70

jlampka · 11-17-2021, 12:19 AM

Nice truck! I have a 72 GMC 3500 1 Ton Fleetside with 8 1/2 foot bed.
What are your plans with your long stepper?

Husker · 11-17-2021, 02:32 PM

Forrest Service truck. Looks like a nice truck.
