I have a 1960 GMC 1002 that was a very early production out of Pontiac. The original owner, now 91 flew up there to get the truck in late 1959. When I took the truck apart, I was pressure washing the frame when these red numbers started showing thru the crud. I am also a member of the 6066GMC Club and have asked around there. No one else seems to have them. I am guessing some rails got the numbers, and others did not. This thread has shown me that Chevy and GMC had the numbers. Here is a picture of my numbers. Any help with the decoding much appreciated. Thanks and glad to be here, GM

Thanks Lostmy65, Forgot to mention the first line, 1002&1502 STD was for 1/2 ton and 3/4ton Standard Transmission Frame. The next row is probably the manufacturers code for this particular frame rail set. The last four digits offset to the right on this line, I am guessing, are the number of rail pairs. The last row is September 26, 1959,which I suspect is the date the frame rail pair was completed. I would bet that Chevrolet frames also could have these codes, but to date, I have not seen any. Come on Chevy guys, give em up, haha. GM
