Zip lock bags! All bolts, screws & fasteners go into a Zip Lock bag that gets labeled - don't be stingy on the description!
Strip the Zed down to a bare shell.
Media blast shell on Rotisserie. Undercoat in an Epoxy primer. Perform rust repairs. Perform any body modifications you wish to do. Refurbish brakes, suspension, & driveline. Before paint, 'dry build' the Zed to check that any modifications you've made from standard will work/fit. Strip shell & paint. Rebuild. My big advice - take your time & enjoy the process. If it takes 2 years, it takes 2 years. Oh & get all the FACTORY steel fasteners, brackets etc re-plated...
