I need advise. A friend of mine that helps me out with welding decided he would build a 68 camaro. It has no rockers,partial floor pans welding in. no trunk pan or rear frame rails or quarters.He got started by welding in repo frame rails and trunk pan.then hanging the rest of the sheet metal. Naturally nothing fits or lines up.I don't now how to straighten up this mess nothing was braced up before all those parts were cut out.I'm thinking starting with the door with new pins and bushing and using them as a reference point .Then install the rockers??? This is over my head, using all this repop stuff and trying to get it all lined up is way out of my comfort zone. Guys please help me out. THANKS
