11.75 rotors, 4 piston calipers, A-body spindles

[68-500]

Ive been reading on disc brake swaps lately. I don’t think these 3 parts where ever offered together. I cant find what cars had 11.75 rotors, Ive looked on rockauto and they dont list an outside diameter for cars from the mid-late 70’s that I suspect came with 11.75 rotors.
Im pretty sure the 4 piston calipers where a 68-70 B,C body thing.
Then I need to find the 73-76 A-body to get the tall spindle.
I wonder if there is a way to mash the 3 parts together.
I guess Im kind of rambling, Im not interested in any aftermarket brake kits.

4 piston was older b/c bodies and -72 a's. Try the info on this.

66-69 B bodies were BENDIX 4 piston calipers.
66-68 C bodies were BUDD 4 piston calipers.
65-72 A bodies were Kelsey Hayes 4 piston calipers.

And NO, you can't mix mash different systems together to make something work out.
Can't be done.

They never made a wider caliper adapter for A or B body 4 piston and 11.75 rotors.

I don't know the rotor dimensions of a 66-68 Budd rotor.
