Can anyone identify my frame - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The mechanic that worked on it guessed it was a 77 or 78.

It's been cut to a short step side. It's 4x4. My parking brake cable look similar to K5 parking brake mounts.

No frame numbers stamped into it? My 84 has VIN's all over the frame. I've counted at least 3 places.) That would be a good start to tracking your birth certificate down.

It has this number. I could also try running my fingers along the top of the frame to see if I feel other numbers stamped in.

The end of that looks an awful lot like a date to me.

That's a part number and date code.

The partial VIN will be on the top of the upper flange of the frame rail.

Oh so the frame is 1976?

The frame might have been too dirty to feel for other numbers. I'll wash it tonight and try again.

I'd take a mirror and check the top of the frame rail under the cab. and under the bed Back to where the tank used to be

I couldn't get the link to work but this screenshot should give you an idea of what the vin should look like on the frame.

CFJ175757, where:

C = Chevrolet (T=GMC)
F = Model Year (A=1980, B=1981... F=1985))
J = Final Assembly location (J = Janesville, F = Flint, 1 = Oshawa, etc)
175757 = sequential portion of VIN, starting with 100001 (GMC may start with 500001)
