Re: How does a pre-1972 SPID designate GMC or Chevy? SPID example for GMC?

After studying the decoders a bit more, the difference GMC and Chevy is more than just 5 VS 6 serial numbers. For starts, a 1971 GMC has a 13 character VIN while a Chevy has 12 characters.

Real Life Examples:
CE141Z654XXX
C 2WD
E V8
1 1/2 TON
4 PICK-UP
1 1971
Z FREEMONT
6 DIGITS SERIAL #

KE141Z654XXX
K 4WD
E V8
1 1/2 TON
4 PICK-UP
1 1971
Z FREEMONT
6 DIGITS SERIAL #

If the K truck was a 1971 GMC and all else equal, then the VIN would read:
KE104?Z1XXXXX
K 4WD
E V8
1 1/2 TON
04 FENDER SIDE
SPACE FOR DESIGNATION LIKE WHAT?
Z FREEMONT
1 1971
5 DIGITS SERIAL NUMBER

With assys, the guide accts for 1000s details such as OEM identifications& part numbers, written in short order. 700+ images include assm, illust., charts, and points of interest. Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
