Can 68-70 B/E-body disk brake assemblies (less the spindles) be installed on an A-body if using 73-76 A-body spindles? nope

There is no 68-70 B/E system. There is a 67-69 B body spindle, and there is a 70-72 B/E spindle. 67-69 B was a bendix system with different caliper and mount and rotor. 70-72 B/E used the Kelsey Hayes system single piston caliper, bracket and different size rotor.

Didn't at least some '70 E bodies have a 2 piston caliper? Seems like I ran into that years ago.
Master, again and still

Dragon Slayer gave you the appropriate year applications above your last post... FYI, the 73-4 E body rotors use the larger inner rear bearing and 1 pc rotors, as do all 73 up disc applications, the 70-72 E/B spindles/rotors use the smaller inner rear bearing and 2 pc rotor, hence 2 E body spindles, the 73 and up B body spindle is the "tall" spindle, similar to the F/M/J body slider caliper spindle....

Ok, so if I use the B-body assemblies including the B-body spindles, will there be any issues regarding the upper or lower control arms? These would be going on a 70 Dart which currently has sbp disks.
