Just got my 2 owner 71 Blazer last week. Will post some pics later. It's a basic model with 4spd, AM-FM, no bench seat, full wheel covers, and a double wall top. It has some rust issues of course for a PA truck. I was wondering where to start the body work? Do I put new body mounts in temporarily to level it before I do the rockers and boxes, and A pilars? And do you put shims in the door openings to keep everything gapped correctly Any ideas or suggestions would be appreciated. Also who sells the best replacement pieces?
