Disc Brake Convertion

The brackets will work. The spindles, maybe. I used the '73 up B body spindles, and I can detect some bump steer. Mind you, my Valiant is lowered and I am running a short and wide tire on the nose. I haven't had time to go back through and check my steering box and idler arm for position yet, so they may be the cause of the twitchiness at freeway speeds. For me, I'm ok with it, I feel that the slightly taller spindle may actually be helping my camber gain in a turn, and it does corner VERY well. Would I all inclusively recommend it to everyone. No, there are the possibilities of potential problems that could range from bump steer to over angling and stressing of the ball joints. If you can find the proper arms and spindles from a donor 73-76 A-body, get it. You'll be rewarded with factory engineering that should lead to years of trouble free service. Short of that, there are several folks out there that make quality tubular upper arms and Master Power Brakes is now back to making reproduction spindles. (So I've heard). Were I not a cheap old fart that had old parts laying around, that would've been the route that I would've taken.
Just my two cents worth. Okay, maybe a buck fifty....
