I have a 85 K5 parts truck that has a good body. I plan on swapping the front clip to my 79. The rear qurater panels on the 79 were also chopped badly by the PO. The 85 has good rear quarters and rear floor. Would it be easier to swap the entire rear or just the side panels? I have never done this before but it seems pretty straight forward. Is there some place to see where the seams are? Diagrams or pictures would be great. The area around the B pillar is a bit confusing. Thanks.
