Any chance you'd make a set of these adapters for a big ford old style flange? The 9 inch rear that I am going to be installing into my 65 Mustang has that flange. I was going to go with the Cadillac Eldorado calipers but I think they are just too large a piston for my Mustang.
Based on the many requests I received, I now have a kit available for the 11.65" vented COBRA brakes from 94-04 Mustang Cobras. These kits bolt to factory 8" and 9" (small bearing), do not change the track width, uses easy-to-find OEM parts, and fits under 16" wheels. Also, installation does not require removal of the axle bearing.
