Additional VIN Locations

[76/85 Truck]

My grandpa swapped a 1985 2wd 1/2 ton body onto a 1976 3/4 ton 4x4 Chevy frame when he owned my truck... 3 years ago when I bought it from him i noticed the registration had the 1985 GMC VIN on it....

Does anybody know how I could recover a VIN number off the frame of my truck? I looked around and I couldn't find the full VIN anywhere...

Thanks!!!

Yes - top side of the upper horizontal flange of the frame rail, midway along the frame (like in the vicinty of where the seat would be). The only thing is I can't remember if it's on the driver's side or the passenger side rail. I wanna say passenger side.

The next time someone corrects me on this I will make sure and write it down.

Now - to answer the question you didn't ask - if it's registered as the 85, as a result of the newer cab being used - it might be best to leave well enough alone.

I wouldn't recommend you try re-registering it to the '76 VIN or anything like that.

Thanks! So I would have to take the cab off to see that VIN, correct? I was going to decode the VIN to find some out about the 76. Thanks for all the info!

No you can see it with the cab on i can see it in my head but man i cant remember where the exact location is. Im going to throw it out there but i wanna say if you look around where the e-brake hooks are your going to see it. I havent been under my truck in a year so memory gets fuzzy... dont tell anyone havent changed my oil in a year

I went almost a year without changing mine, but then again mine has a "self-changing oil system". It used to leak/burn (the valve umbrella seals are bad) about a quart every 2-3 weeks. So I just add accordingly.

So is the VIN on the very top of the frame rail? And is it the complete VIN? (All 17 letters/numbers?)

Thanks!!

Thank you!!! I'll check next time I'm under the truck... I wish my grandpa would have kept the 76 body even though it was covered in rust... I would like to know the RPO codes listed in the jockey box...

I think the core support is from the '85... he replaced the front clip, cab, and box. I'll check it out.. Thanks!

Not that I'm aware of.

What are you thinking of? Is there a label (like the emissions label) or are you thinking of stamping?

It's stamped on mine. I will snap a picture if i decide to open my hood anytime soon

I've got a 79, and the vin on the frame is NOT a complete vin. Mine has the first letter (I'm assuming to tell the difference between a GMC and a Chevy frame, because if the cab wasn't attached, how would you know?) and the last 8 letters, which is the year, the assembly plant code, and the then the last six sequential serial number.

This was also similar to other GM trucks I found in the junkyard. I've never seen a complete VIN on a frame.

On my 79 GMC it's stamped on the top of the passenger side frame rail about a foot behind the cab. I think it's the full vin but I will check tomorrow.

Thanks for all the replies! Hopefully this weekend I can find the time to check the frame rail for the VIN number. I'll let you know what I find!
