Oddball car - swap to disc - ideas?

Backtobasics said

Great info. Is there substantial difference between the 10.98 and 11.75 rotors? All I have seen are 5th Ave in my area.

While I understand there is no signficant reason to move away from drums, fact is I don't have drums. I have a naked 8.75 that is going to be cut down. I will have to buy aftermarket axles. I will need brakes. Since that is the case, and I don't like seeing the drum behind a nice wheel when it's nearly the same work (for me, in this case), I might as well go disc, and paint and detail to my likings....

Thanks for all the insight and opinions.

There's about a 9% increase in braking force going from the 10.98's to the 11.75's, just because of the rotor diameter (larger lever arm acting on the spindle). A-body's also used smaller diameter pistons in their calipers, so if you use the later B/E/R body calipers you get an additional increase in braking force compared to the A-body calipers. And then there's better cooling because the larger rotors, while having the same brake pads and therefore the same brake pad area, have a larger rotor surface area (and swept area).

Does that also mean he might have the small ball joint control arms Rusty or is there a firm cut off on those?

1972 should have been the last year for the SBJ UCA's. 1973+ should all have large ball joint UCA's, even if they had SBP drums in the front (which would have been 10"). Now, this is Ma Mopar we're talking about, so how firm a cut off that is would probably be open for some interpretation.
