The back of the suburban quarters curve in, so I had to cut a set of truck quarters (thanks BowTieOgre!) to weld to my bed ends to make everything come together at the bottom. If I were to do it again, I would get more of the truck bedsides and it would have saved some welding (but would have been a bigger pain to fit). Then I started cutting everything in, and yes, I cut off part of the new rear quarter that I welded on about 6 months ago,
