were any C10 trks ever 4x4 or did it have to be a K10, 1970
If I am thinking right I don't think the K searies came out untill late 1970' s
Since 1957, trucks were available from the factory as 4-wheel drive, and the new class scheme would make this known. A C (Conventional) in front of the series number would indicate 2-wheel rear drive while a K would denote 4-wheel drive.
both answers are correct. they started the C or K to denote 4X4 in the late 70's. in your year The C was availible in eighter.
The 1960 half-ton models were the C10 and K10 short-bed trucks, and C15 and K15 long-bed trucks. The 3/4-ton C20 and K20, as well as the one-ton C30, were also available. GMC did not use the "C" nomenclature, though their 4x4 versions had the "K" designation.
What Tenspeed said, C=2wd K=4x4. People might modify a C10 to be 4x4 or a k10 to be 2wd but it's not factory and requires some fabrication becasue the front suspension setups are completly different.
C10 came factory as as 4x4 it wasn't till late 1970 that Chevy came out with k10 distinction
the "K" designation was used from 1960 and on. Prior to 1960 4x4 was and option through another company, i cant think of the name right now... However I could see the same company converting c10's for a while longer. Also I've seen plenty of converted trucks from 2wd to 4x4. I also know of a 64 k10 truck personally, so I know they used it for sure as early as 64
I Find The Last Comment Difficult To Believe Since I Have A 1970 C10 4 Wheel Drive With All Matching VINs.
The c10 in 1970 came in 4x4 The K wasn't used until 1971 and some late 1970 trucks
