I been looking through old binders and I found the pictures. What Wally used was 944 bakplates with handbrake, turned down (to 117mm outside diameter) type 4 stub axles, custom aluminum adapter plate between stub axle and rotor witch was a 944 Turbo 298x24 with 71mm height. Calipers was as I recall from C2.
I’m going almost same direction but I am using 944 NA rotors 289x20 / 71mm height - and Boxster calipers. I will take pictures and upload as I’m going ahead.
