Frame vin decoder - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Mikemelton · 11-02-2021, 08:55 PM

I bought a frame to swap under my ‘65 and can’t seem to decode the vin. Number on the frame is 6A120287

**The Rocknrod** · 11-02-2021, 09:13 PM

Is it a Canadian frame? https://67-72chevytrucks.com/vboard/...84&postcount=2

Mikemelton · 11-02-2021, 09:42 PM

I have no idea I bought it from a guy in Mississippi and it had a 64-66 cab on it is all I know.

**cwcarpenter98** · 11-03-2021, 12:11 AM

My truck has a partial vin on the frame that matches the cab. I can't remember what number comes first, but I can check again tomorrow

Plant designation for Chevrolet on our trucks, GMC may be different.
Wait - a 72 Burb I see had a last numbers of 2Fxxxxxx, maybe it's a 76 built in Atlanta?
Mikemelton - Post a couple pics of the frame please.

This is the only one I have before taking it apart and adding ’86 suspension

Mikemelton · 11-03-2021, 12:33 PM

Starting rebuild

**The Rocknrod** · 11-03-2021, 02:18 PM

It's a latter model unit with that trans cross member and a-frame bushings. My guess is a 76 built in Atlanta, the last six number are the sequence numbers.

Did you mean ‘66?

Mikemelton · 11-03-2021, 05:05 PM

I know it has ‘86 belly Pan and front suspension on it I put that on it

That's where your throwing us off. Post a pic of the numbers your quoting in post #1 on the frame.

Mikemelton · 11-03-2021, 05:53 PM

No, not with that VIN stamp.
Does a 66 bumber fit on the front frame rails? And were they welded on there?

Mikemelton · 11-03-2021, 06:28 PM

Yes bumper fits nothing has been modified until I got it

**cwcarpenter98** · 11-03-2021, 07:18 PM

My guess is you have a 66 frame that was made in Atlanta. The numbers after the A would have matched with the serial numbers on the cab vin.

My truck is a 63 built in Atlanta, so the frame vin is 3A124779. Those last 6 numbers match to the last 6 numbers of my VIN, so I know my original cab is sitting on the original frame

**The Rocknrod** · 11-03-2021, 07:37 PM

Yes mine is a 64 with a 4S218076 number on it. I dont know why I didnt just look at mine.
I drink in the morning so...
