what is the difference
« on: February 25, 2007 - 07:42:54 AM »
 Right know I have 72 challenger disc brakes on my 70 they are 10" with the separate hub design. I wanted to go with the 11.75 discs so I was told to go with 73 to 76 A body 73 or 74 E body spindles. So I got a set of 75 A body spindles when I got them home I checked the mopar action disco tech article for the spindle measurements and they were correct. The problem is I had an extra set of bearings for the 72 spindles and they fit right on the the 75 A body spindles. Now I thought the inner bearing was supposed to be bigger on the 75 spindles both spindles have the 1 3/8" inner bearing so know I wondering what is supposed to be the differance :dunno: :clueless:

They might be a late production run from 72, so they really are 73 spec.
