Put some up on 2 walls of your garage. Paint it white. Go to Lowe's or Home Depot and buy a bulk pack of pegs. As you disassemble a section of your car, hang it up carefully on the pegboard on the "dirty" side of the garage. Get some organization bins. Hang them to the pegboard. As you take bolts off, put them in containers and label them. When you have some downtime from any major work. Grab a piece off of the "dirty" side and sand it down to get ready for paint. Once the piece is done to satisfaction, and ready for reassembly, put it on the other section of pegboard. If you do it right your wall will look like a model-kit you assembled as a kid.
