You likely have local craftsmen that can pound out dents and rechrome stock unobtainium-bumpers. They are quite thin and un-dent easily. Warning- they also dent even easier! Shops make a lead mold matching the inside & outside, and use those to erase dents with small hammers. This also works for dented ss body trim, too. There are reproduction bumpers of stainless steel & fiberglas, but rarely original chrome-on-mild-steel. There are 2 versions (rounded inboard edges vs sharp inboard edges) if you decide to replace them instead of repairing.
Check & thoroughly clean behind the fuel tank- which will require pulling the engine and ZF to get the tank out. Perfect opportunity to refurbish all three assemblies. If they've never been disturbed, all WILL need it. If someone has been in there before, check even closer! All or most parts are readily available from U.S vendors, including refurbished stock magnesium wheels. None are cheap.
Save your money on factory doc's. The factory Euro build sheet will tell you when your car was built, the factory paint color, tire brand & size and the stereo brand & serial number (if one was factory-included). That's about it- for $200 or so. Marti reports apparently only cover cars sold in the U.S (maybe Canada). Ford scrapped most of their records in the previous century. Your car was likely built in Aug or Sept 1972- coming up on 50 years ago. Welcome & good luck.
