I have no personal experience with kits, only with the oem Mopar stuff, which, IMO, is perfectly adequate for a streeter.. I prefer the fixed calipers on account of I've been driving them for a few decades with no problems. All my other Mopars have been floating caliper cars, and they do Ok in their applications. You can retro-fit the 73 up system pretty easily and that system was in production for decades,on all kinds of Mopars,so their are plenty of cars to pluck one from. FMJs and Darts are easy pickings.
