Maybe. 1973+ was a strange year for front drum cars. There is info on here if you search. I forgot the correct answer, but it is something like "all drum cars still had SBP wheels (5 x 4" bolt circle)" and "73+ drum cars had a different spindle than 1972- drum cars". The later might mean that it used the 1973+ larger ball joint. If not, you can get a tapered shell the slide over the smaller ball joint stem to fit the larger hole in the spindle. FMJ cars used the same shaft size upper ball joints as 1973+ (thus spindles fit), but the rest of their UCA is apparently different. Of course, their LCA was much different since they had transverse torsion bars.
