thanks guy. Personally I am only interested in GMC SPID's for 1965-66 GMC's. I own a '66 short bed that was built in Sept '65.

You are right on Chevy C10's. There are dozens of SPID's posted. I would not recommend they be posted here. We don't need to take up that much space on the 6066 forum.

Ill probably start a new thread someday. I'm also interested in block pad stampings (on head in front of distributor). I've had difficulty decoding. I may not have original 250. Block and manifold casting numbers, and door jam VIN #s are easy. JOLLY did some of that work already.
