Just found out today from a friend, 78 Camaro rotors and bearings will fit on 65-67 Mustang drum spindles. This would definitely be cheaper than the conversion kits offered. Also, a 75 Corvette master cylinder bolts in the Mustangs. Hope this helps someone save a little money, the Granadas are getting more difficult to find for parts, but there are a LOT of Camaros and new Camaro parts available.

 

what are you doing as far as calipers and brackets? The bolt pattern would be the big downfall, chevy rims on a classic mustang....

 

Use Metric calipers and make your own mounting brackets! The brackets just need to be a stout piece of steel that positions the caliper in the correct position. Keep in mind, I haven't actually done this conversion myself, this way. I have only done it with Granada spindles, where everything just bolts up, like factory. If you have specific questions regarding geometry and caliper bracket placement, I will ask my friend for exact measurements to post here, as he did it after checking the prices for a ready made kit. Let me know?
