Disc Brake Convertion

The only way to see if the caliper brackets will fit is to bolt them up. I just installed 73 Duster disc brakes in my 66 Valiant. I put the calipers to the rear side of the spindle, normally it mounts to the front side. You do this because an aftermarket sway bar will hit the brake calipers when mounted to the front. The 73-76 Duster spindles will work from side to side, not effecting the ride. I would use these spindles, then you will also need the upper control arms, they have a different larger balljoint. You will also need lower balljoints from a 73-76 A-body. It is a simple swap! Good luck, Keith.
