Didn't at least some '70 E bodies have a 2 piston caliper? Seems like I ran into that years ago.
No, all 70-74 E body used the single piston 2 pin caliper.... 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....
