Frame Identification
I just purchased a 1965 "C20" to restore. Turns out, the vin # on the cab and the title confirm it is a 65 C10. The problem I am having is that the serial number on the frame is behind the cab on the passenger side top frame rail. I know for the 65 that the serial number should be either on the driver side frame rail right in front of the upper a-arm or on the driver side frame rail underneath the cab. The first part of the serial number is 1CAZ..... I haven't been able to find any chevy frame identification numbers that start with those particular letters. It is a coil spring/disc brake front end with leaf spring chevy 14 bolt rearend and it is 8 lug. Any help is greatly appreciated. I want to make sure I get the correct parts for the chassis and suspension.

Re: Frame Identification
The frame ID # should be the same as the VIN# found on drivers side under cab.

Re: Frame Identification
I've looked in both places and have no vin# stamped on the frame. The only one is on the frame, under the right front side of the bed. I'll post the complete number when I get home tonight.

Re: Frame Identification
Pictures would help a bunch. Show the cab mounts.

Re: Frame Identification
the frame is a GMC frame usually if it has rear leaf springs.
they do not put the whole vin nbrs on the frame. the last 5 or 6 digits from the frame sould match the last 5 or 6 on the vin plate. that is the production # and that shpo;d match. GMC frames of these years did not seem to the ser# on them. sounds like someone perhaps stuck a GMC 3/4t frame umder a Chevy c10 body this is what happens when these guys cobble all of this crap together and dump it off on someone witout doing the proper registration ron |

Re: Frame Identification
Well, I spent all night looking online for anything that could tell me what year this gmc frame is and i found nothing. The last 6 digits don't match the title or vin plate because the title is for the 65 c10 cab. I'm not sure how different the 3/4 ton frames were between the different years of gmc trucks but I just don't want to spend money on parts that are for the wrong year.

Re: Frame Identification
Hug,
I agree that it doesn't line up very well with any VIN scheme I can find for GM. "1C" looks like the beginning of a '61 Chevy VIN, but it wouldn't be followed by two more letters. The two letters together looks like a GMC VIN, but it wouldn't have THREE letters. '72 vins DID have 3 letters, but I can't find any reference to "A" being a valid letter in that position. Two thoughts -- is it possible that it's NOT a VIN but a part number? And second -- it's also possible to identify a frame by the dimensions of the frame members. That information is well documented. Care to post a picture and frame member dimensions for us to cross-check? Brian |

Re: Frame Identification
Front cab mounts are intact. Rear cab mounts have been cut off. Truck does have power steering but didn't come with an engine. I have a 4 speed manual transmission that came with the truck but who knows if it was the original one. I will try and move the cab off of the frame tonight and post a picture of just the chassis. Thank you everyone for your help.

Re: Frame Identification
The more pics of the frame the better. The front where the bumper mounts also helps.

Re: Frame Identification
I didn't get a chance to pull the cab off the frame last night but I did get some pics of the bumper mount and front of the frame. I'll try and get the cab off tonight.

Re: Frame Identification
This thread has dimensional drawing of all years 60-66 frames. Do your frame measurements line up with the '65?

Re: Frame Identification
I agree. It is a '73+ frame.

Re: Frame Identification
Just out of curiosity, what indicators from these photos would identify this is as a 73+ frame? I'm always trying to educate myself so when looking at these trucks for friends I can spot the differences in various years.

Re: Frame Identification
What I see is the shape, the formed section for the power steering, the spot for the brake lines for the front disc brakes, The body mounts and the bumper slopes the other way.

Re: Frame Identification
So we're definitely looking at a '73-'80 3/4 ton chassis?

Re: Frame Identification
I'm not a frame expert but it does look like the frame horns aren't 63-66. But those lower control arm bushings look like pre 73 with zerk fittings.
