Both are 3/4 tonners. K is a GMC and C is Chevrolet. darn! I wish I was closer so I could try my rim on your truck, Denny. Ought to be the same thing, and my guy said they're everywhere. Clearance to the tie rod is minimal, mind you, but there. I've packed at least one 4,000# payload since I put them on, so I know they work.
