The Stovebolt Site Forums The Shop Area General Truck Talk K10 or K15

I have a 63 GMC 4x4 pickup and Im having trouble getting brake parts its titled k10 when I try to get parts they ask if its a K15 it has 6 lug wheels does anyone know if they made a k15 (3/4 ton I guess????) with 6 lug wheels?

A GMC 1/2 ton 4x4 will be a K15. GMC used a slightly different numbering system that Chevy,with the numbers ending with 5 instead of 0. Where the Chevy would be a 10, 20, 30, the GMC would be 15, 25, 35 for the same range truck, The only exeption was the Jimmy, which was a K5 just like the Blazer. I'd say somewhere along the line, the truck got titled wrong, easy mistake to make.

Seems I made an error. GMC changed to the numbering system I posted in '67. Still, 6 lug would be a 1/2 ton.
