Can any one out there tell me the most logical steps in replacing rusted out rear inner fenders? I am doing alot of parts replacement on the rear of my 70ss. I have new quaters (full) new outer fenders and in the process of replacing R&L trunk floor and the inner fenders. I am going to replace the filler between the trunk lid and rear window as well as the rear package tray. I am sure there is a proper most logical steps in doing this, but am not sure what to do first. Any suggestions?
