Finally Got My Dart

Consider just "fixing what is there." Find out what brakes are on it. Is this an original 340 car? Then it should have come with decent brakes. If that is what it has, AKA the brakes native to a 340 car you should be able to get them working well. If it has drums, they might be worn out, not just rough, but worn too large (or turned too large) and so the shoes don't fit right. If you are not going to race it or drive it hard "a lot" that might be a better "fix."

Thanks for all the great comments. It is not a number matching motor/trans the way I understand it. The car came with the highest output motor for that year. My guess is that it was pulled and probably sold, but who knows. As for the brakes, all around drum brakes, they stop the car but it seems very slowly. One of the places that popped up in my google search of drum to disc conversion was TheRamManINC.com - some good information but I can't believe the cost of this project. Also, I want to stick with the 5 X 4 bolt pattern because to switch means having to buy all new rims and tires which aren't needed at this time. He also is one of the few that offers a 5x4 bolt pattern rotor with his kit and it is all a "bolt on" fix. I welcome any and all comments on this...as I said I have almost no experience with brakes (let alone converting them). On the a/c issue - I have not found anyone who will support the R12 refrigerant, plenty of people that will buy it but not sell it. I think I'm going to run up to PepBoys to see if they can do anything for me. I'm also not sure if this is the right place to discuss this so if it's not I will change where it is.
