71 dart disc brake swap

professor is that the 76 only year for f m and j cars

Oops, meant to say '76 and later F/M/J. I'll fix that in my post.
And as someone else pointed out, some later B & E body stuff used the same spindles/brakes as the late A body parts, but you still need to use the large ball joint late A body upper control arms with them. I'm not sure which years it applies to for the B & Es. I just speak A body fluently, and only pigeon B & E body... :rolleyes:
