10" Drum brakes on Early A

As long as you're using A body brakes, it should fit no problem. In the front you'll need the 10" spindles and hoses, in the rear the lines should match up to the new backing plates and cylinders. You *may* need 14" wheels (minimum) to go with the new brakes- I think the 13s will still physically fit, but it doesn't leave much if any room for cooling.
