donor truck year compatibilty

Are you referring to the front fenders? 67 and 68 fenders are the same with the exception of the marker light. You said your truck is a 70 which means you could use front fenders from 69-72 and they will all work with either a 69-70 grill or a 71-2 grill. As far as the brake lines, I'm not sure the differences but I do know that 71-2 trucks had disc front drum rear. I would say if you could find a nice 71-2 lwb truck for a parts truck you'd be in the clear.
