65 impala disc brake swap
hi everyone,hopefully someone can help me shed some light on my situation,I recently purchased a set of disc brake spindles ( GM 3966187 CASTING #) calipers(5488316 GM casting #)and large rotors measuring 11 3/4 across with a stamping on it century R30003.This combination was supposed to be from an impala from 66-70,the problem I'am having is identifying the spindle because I did not get any spindle nuts dust caps or tab washers I thought it to be no big deal until I started to look for spindle nuts the spindles have the large outer bearing .850 which I was told to use but the thread is not the standar 3/4-20 size that I havefound to be common,the crest of the thread measures aprox. .850 and the root is aprox .800 the spindles seemed to bolt right on with no problem and look like they will align okay,also found another stamping number on the spindle (GM 72A) I'am thinking these might be from a Monte Carlo or other A body.if some one could help identifying these spindles it sure would help,I hope I haven't wasted a bunch of money trying to save some money,thankyou any info would be great
