Z32 300ZX and R32/33/34 Skylines. I know , they are not toyota.
I can check the mounting hole dims on the 300Zx ones, as that is what I am using. But if you stick with the MA61/MS123 disc, the Nissan ones will be hard to fit due to the leg length of the caliper mounts.
MA70 are single piston rears.
SW20 early are single piston and have the integral handbrake. The later ones are 22mm, but neither will fit as the body is too 'deep' and interferes with the rear shock. Been there done that
I think the beemer rears are single piston as well.
