I'm looking into converting the front drum brakes on my 1972 Satellite to disk and I'd like some advice on what donor cars will work. I think there are several cars that use compatible parts and I'm on a budget and have the time to search locally for the used parts

 

Wilwood sells a new pair of front discs with a lot of the included hardware for $682.95 but I don't know what kind of budget you're on. The B and E bodies are the same as far as front discs are concerned, so you may be able to harvest from either. As far as the stock brakes are concerned, you should take a look at this site http://www.moparaction.com/tech/archive/disc-main.html. Hope this helps!
