74 spindles and 11.75 rotors

Dartnut said

Just curious, so what i get from this is that the bigger disc brakes from a '73 to '83 b body will fit the '73 and up spindles with no changes other than the rotors, calipers, and the caliper mounts?
I take it that the minimum wheel size would be 15''.
Correct?

Yes. If you match the type of caliper you have to the 11.75 bracket, you don't even need new calipers. So, if you're got slider calipers, just get 11.75" slider caliper brackets and re-use your calipers. Otherwise you'll need calipers too.

Minimum wheel size is 15", the 11.75" rotors will not fit 14" rims.
