I know you are talking about a frame off restoration but I would like to caution you on the time and the cost of restoring a rusted out car. I just recently sold a 60 Impala convertible that I owned for almost 20 years. I never did fully finish the restoration but I put more money into that car then I could ever hoped to have gotten out of. If this bird does not have any major sentimental value I would sell it and find a better project car. They are out there and well worth the search. Once you start down the road rust the cost just keeps climbing. I would suggest taking a few steps back and really look the car over before you do any work. If this is your first restoration look for another car.
