I happen to be the world's foremost procrastinator, more discussion on that at a later date.
Ok, long time ago on those pics, I kinda lost interest and never finished the project.
Late 90's Cobra rear rotor, caliper BRACKET, pads. SHO 93+ CALIPER.
Custom made rings to center the rotor, custom made (not really made yet) backing plate. Re-drill the rotors.
I believe that John over in Cleveland had all the parts made, not sure if he put them on his SHO or not.
