Nice car, but yes, the front control arms were bare steel from the factory. From the pics, it appears all of the "bare steel" components were painted; rear end, drive shaft, sway bars, springs, brackets, etc., etc. Can't tell on the rear upper and lower arms, those were galvanized from the factory.
There are also several components that were zinc dichromate from the factory and appear to have been painted; fuel filter bracket, alternator pulley nut, etc.
There are a few "paint daubs" that I have not seen before; i.e. the yellow on the muffler hanger brackets.
A lot of work put into that car. Good money, but wasn't he wanting more than that on eBay a while back?
