Greetings from Alabama

As far as the brakes, find an A body 73 up with discs, get the whole setup including the upper control arms, master cylinder and proportional valve and it will bolt on. you are now gonna have 4 1/2" bolt circle on the front, so you should also do something about changing the rear axle to 4 1/2".
I plan on doing this to a 66 Barracuda if I can get some health problems straightened out,and finish my 63 sport fury ragtop. Already have the parts gathered for the cuda,with new rotors and calipers,along with a complete front suspension kit.
I am in Haleyville, btw, about 75 miles nw of Bham.
