I don't know about the 87, but my 83 C20 has an i.d. mark on the right (passenger side) frame rail on top, about the midway mark of the fuel tank.

Re: Frame-chassis s/n???

Should be the same on an '87.

Tucson - that is an excellent picture.

D = '83
J = Janesville
Serial number = 14268x (covered up by the mount).

Re: Frame-chassis s/n???

It will probably vary slightly based on assembly plant, but should be pretty close.

Re: Frame-chassis s/n???

That is a rubber bumper I had to install on both frame rails to cushion the drop of the dump box conversion. The "professional" installers did not install them when the conversion was done, so the box dropped with a big bang no matter how gently I let the box down. I am on my second set, going for a third set, due to desert heat helping to squash them down. The trim line of the box sets up a little bit in front because of the extra height the bumpers provide, but nobody notices it on my beater truck.

Except for 73-75(?)'s where one number was on the driver's frame rail around the steering box area. Later ones had 2 numbers, one under the car and one under the bed, both passenger frame rail, within 12" of each other or so...
