Frame number on a 1973 GMC 3/4 ton
« on: June 22, 2021, 06:20:52 PM »
I have a 73 GMC 3/4 ton that I had bought for parts, so I didn't register it.  Much later, I decided to fix it up and make it a running driving vehicle.  Problem is, I put another cab on it, (the original was rusted, as many 73s are), so there is no VIN on it, and my paperwork was lost in a garage fire.  I can't for the life of me find the VIN number on the frame.  I have been told that it is on the driver's side rail under the cab, that it is on the right side, that it is just ahead of the right-rear cab-to-frame mount, that it is just ahead of the the left-rear cab mount, and I have looked in all those places, but I can't find it anywhere.  I have unbolted the cab and raised it up and used a mirror, and STILL can't find it.  HELP!

PS:  When I got this truck, it was an automatic, but I put a manual trans in it.  Could the numbers I am looking for be under the transmission crossmember on the driver's side?

Did you save the vin plate off of your old cab? Look by the steering box on the frame rail.

I had saved the vin tag from the rusted cab, but it has vanished.  You think the numbers are near the steering box?

Look hard for the VIN plate and hopefully you find it.

I have torn the house apart, and so far, still can't find it.  I sure hope I do.

Check the right hand drawer of your tool box
