I have an 88 k-5. Right after I got it it sat for about 2 years. I am now driving it and recently crawled under it and found that it is rusted to high hell. The pass seat is about to go threw the floor, rear area is rusted under carpet, It is pretty bad. I love the truck though and was wandering would it be easier/cheaper to buy and another k5 w/ a bad motor but good body and just swap all my good pieces or just go ahead and have the rust cut out and new metal welded in?
