[GMCNUT]

So to speak to the purpose of the two VIN tag holes in a 1000 series GMC trucks' door frame; they are stamped out as part of the manufacturing process for that piece of sheetmetal which was indeed used on constructing Chevrolet cabs, and larger series GMC's where a different type of VIN plate may have been used. I checked my 1960 parts truck and it came with the kick panel tag and I also called a friend who is a local expert on early "knee knocker" trucks and he's never seen a 1960 GMC with a door post VIN plate. So, unless someone can provide proof of a US made (Mexican or Canadian assembly plant produced trucks very well might have had a door pillar mounted tag) 1960 1000 series pickup coming with a door pillar mounted tag I think its safe to say that all 1960 1000 series trucks have the kick panel mounted VIN plate like the 55-59 trucks had. 1961 is when I believe GMC went to the slimmer tag mounted on the door jamb.
