Scarebird Brakes

I know you can get the rotors and calipers for stock mopars. but they will probably have to locate them and then ship them to you taking more time. you can go to the parts store and have the part either in stock or sent to the store next day at no extra charge. sure beats waiting a couple days for a part that might be available for a few more years.
I have done the 73-up disc conversion and have had to wait days for parts.

where the hell are you shopping? most i have ever had to wait for 73-up parts is a few hours at the local napa.. the parts are still readily available. in 30 more years why knows what will be. not to worried about that though. :)

exactly how much longer will the 73 and up stuff be available, this may be the way i go soon might as well go 4.5" and then use 15" rims so i can find tires!

spindles, upper control arms, rotors,brake pads,bearings/seals, ball joints and bushings are all available new so i suspect they will still be around for quite a while.
