New Disc Brakes and 14 inch Ralley Rims

Or you can try this http://www.performanceonline.com/19...AR-DISC-BRAKE-CONVERSION-KIT-SWBKS6274-19537/ . Everything you need and I'm sure you can get a master cylinder at your parts store with the money you save....

That one says 15" wheels required.

If the vehicle is already big bolt pattern, then 73+ A body brakes are the cheapest way to go and it's not like you're skimping out on quality either.
