Can't help on the body/paint question, but another local carb place woth considering is Joe's Carburetors in Lynnwood. 5516 186th Pl SW Lynnwood, WA 98037, (425) 774-5504. What kind of carb is it? Unless your engine has been tweaked quite a bit, odds are good a 600 cfm Holley or Edelbrock will run too rich unless it is rejetted.
