Im building a 1970 plymouth Duster and trying to find a modern Chrysler product that will interchange with a 1970 Plymouth duster for front disc brake system
Good question, BUT there isn't any. you have to buy a kit, sorry. There are lots of spindle, rotor, caliper kits out there but nothing you can grab off a A,B or C body that will work. Why? well in 72 when disc brakes came out on the A body ( duster ) the spindle size and other thing were different. BUT there are some set ups where you remove the drum, toss the shoes, and install rotors and weld on a caliper kit to what you have, and then again BUT, how safe I have no Idea and then you still have to think about a booster and most defiantly a master cylinder and adjustable proportioning valve. Try Paddock or Wilwood for assistance
I've never heard of welding a caliper in place in anything, wouldn't work right and brakes would be garbage. A proper conversion will include brackets to mount your calipers to the vehicle correctly so they can slide and move like they're supposed to. The best thing to do is to contact several different performance parts companies (such as Summitt, PAW, etc) or check out their websites and see who has the best deal on a conversion kit. A good conversion kit will include all necessary items, including a new master cylinder and proportioning valve along with the calipers, pads, and mounting brackets.
