I was going to ask this later when I got close to doing this, but the point was brought up in another post of mine, so I thought I'd ask now. I have a set of Group 4 wheel arches for my rear section, holding them up to the body section I can see that some of the existing body work needs to be removed. So my question is, is there a pattern available that shows how much needs to be removed. Or does someone have picture of the process, kind of a step by step photo session?
