Front brake noise

[THE STEVE]

last year did a disc swap on my car. got a 72 duster. used 77 aspen spindles with 73 duster upper control arms and duster calipers and hoses. car rolls, drives, and stops great. but... the caliper has a slight bit aof play on the spindle. its held down good with the metal tabs that bolt on the top. but every little bump in the road they make a rattle noise. just wondering if i used the wrong calipers? if maybe theres a slight difference from a 73 duster caliper to a 77 aspen one? or am i an idiot and installed it wrong? everything seems tight and safe but they do move front to back less than an 1/8th inch. just enough to make a rattle. also the balljoints and everything else are brand new.

anybody? took a closer look today and did some tweaking trying to get the hold down brackets to sit tighter on the caliper to keep them from rattling. it helped alot but didnt fix the problem entirely.
