Im looking thru some GM parts lists. Not for anything in particular..just lookin'.
I find that the classification of the girls changes from the 1st gens to 2nd.

There are listings they show for models G1000 GE & GS 1500, 2500.
BUT in the parts they're showing G10 from 64-66 then G15 and G25 for 67-69.
My belief was my '68 90 was a G10. I always tell the guy at NAPA its a G10 when looking for parts. These lists tell me its a G15. ??

Anyway..you guys are the experts. Can anyone clarify?

Thank you!!

I'm not sure if it applies, but usually the *10 designation is Chevy trucks, and a *15 is GMC and so on.

Where does the G12 come in?

A 90 with 5 lug nuts usually makes the van a G10 Chevy or G15 a GMC 1/2 ton van.
To make the difference and further confuse people between Chevy and GMC the number 5 was used on all GMC Vans and Trucks
The 3/4 ton models of vans which came usually only in long wheel base models had 6 lug wheels.
Being able to "special order" or "custom build" a Van or Truck,even cars back in those days helps to muddy the waters even more
The Display Van is a prime example of a fleet custom ordered van
It would not be the first time miss information has been found in service manuals.....


Where does the G12 come in?

Somewhere I've got a pic of the vin tag from the '66 I recently sold. I'm thinking it was G12 and it had the factory 12 bolt corporate with 5 lugs. I'll try to find the pic.....

Edit...found the vin#, it was G1256PXXXXXX
