http://www.summitracing.com/parts/SSB-W120-22R/ there for a 67 cougar or mustang also i guess. anyone know if they'll fit or cars?
I do not believe that they will work. Those are designed to work with the 1967 Mustang and Cougar factory disc brakes. That system used the 4 piston Kelsey-Hayes brake calipers.
How about this; http://www.discbrakeswap.com/Mustang Disc Brake Conversion Kits SWAP2.html It's what I plan on using on my Maverick............which still has the heavy original drums.
Your brakes have 10.5 inch rotors with single piston calipers if they're the stock units on a Maverick/Comet
