[Mark IV]

Alleghany Ludlum Steel built several "stainless" cars with Ford over the years, the one seen here, some 1960 T-Birds and a 67 Lincoln convertible. The panels were stamped on the production dies after model year production had ended as the stainless material tore up the dies rendering them "junk" for futher use. In the case of the Thunderbird, no correct gauge rolled stainlees wide enough to form the roof panel (think roof and "C" pillars flattened out) existed so two sheets were welded, ground and then stamped out.

Yes, all of the major componetry that would have been mild steel (body panels, frame, brackets, bumpers, etc.) were formed from high nickel stainless steel (or as Ford marketed it when first used on bumpers in the thirties "rustless steel") These cars are popular in parades and shows still today.
