I recently bought a 1978 Chevy C10 that is 4 wheel drive. I was told it was completely stock. I have since read that the C10's were all 2 wheel drive and the K10's were 4 wheel drive. What's the deal?

Thanks!

It probably is stock.
"C" was the designator for 2WD and "K" was for 4WD.
But that didn't start till later.
Early to mid-eighties, I think.

Pretty sure C stans pickup and K is for Blazer. Has nothing to do 2wd or 4wd
