Disc Brake Upgrade Reference Thread

[joesscamaro]

I've looked through a lot of threads on this topic and don't think I've read an answer to a question that came to mind today. I'm trying to swap over to disc brakes on the front of my '65, so I went to an auto parts store to get some ball joints for an '85 Chevy. I remember reading on here, that the spindles are different for 1" and 1 1/4" rotors. I plan on running some steelies when I can find them...but my question is...does it matter if the ball joints are for a 305 ci truck? Aren't the 1 1/4" rotors offered only on the 350 trucks? Does this make a difference when ordering ball joints? I plan on ordering spindles for the 1 1/4" rotors. Thanks!
