Here's my progress so far on the 66 Fastback.
C5 Corvette 97-2004 calipers and mounting brackets.
C4 13" rotors. They have more "back space" to move the calipers closer to the spindles for improved caliper to wheel clearance. Used the wheel hubs to layout the wheel stud pattern. Made steel rings to center the rotor on the hub.
1970 Torino drum brake spindles. They have the larger spindle and bearings. According to Hollander exchange the same as a 1970 Mustang but much cheaper.
Was going to use the 70 hubs but decided to purchase the Cobra Automotive aluminum huds. The 70 hubs had some lateral run out I didn't like. I believe if a guy made a mandrel for the hub so it could be set up in a lathe, the hubs could be turned true. The Cobra hubs are very nice but not cheap.
Made the spindle mounts out of 3/8" steel plate. Cold rolled steel.
Basic dimensions are 6"x 6". Used a hole saw to cut hole in the middle so the hub cleared. Used the drum backing plate holes to mount the plate. "Clocked" the caliper so it's on the trailing side of the spindle. Caliper bolts just clear the spindle upright.
Used a separate peice of steel to offset the caliper from the spindle mounting bracket. Had to be milled to center the caliper over the rotor. I will bolt and weld these peices together to make one solid caliper mounting bracket.
Bought drilled and slotted rotors from Rock Auto Inc.
With the exception of the Cobra huds this is a fairly inexpensive swap.
I will try to attach a few photos.
Any comments?
