seriously though, that number works. those guys will either have what you need or can most likely tell you what's compatible. postaljeep.net
as far as brakes go, autozone lists shoes specific to DJ's on their webpage (only ones I know of), other brake parts are *mostly* compatible with a CJ, but might require a little angle grinder surgery now and then... leaf springs/lift kits for CJ are a complete no-go unless you're willing to do a little fabricating here and there. (rear springs on a DJ are outboarded and on pins... everything is just that little bit off...)
I really haven't tried to go matching up what CJ stuff works and what doesn't... as near as I can tell the floorpan is the same, the frame is the same shape but boxed on a DJ, the engines are the same, but the rest of the driveline is not, and some drivetrain components can toss some nice curveballs (I just spent 4 months finding the right slip yoke for my AMC modified torqueflight, a.k.a. "torque command 6")
If you have any aspirations of converting it to 4WD, plan on doing it ASAP, and rip the entire driveline out and replace it
it will save you a TON of headaches, but even with the headaches, the darn things are just too fun to ignore.
Oh, and I ran all my wiring from scratch so I could make sure everything was fused, but you could very easily use a generic harness. the whole thing is barney simple
the stock wiring used self resetting circuit breakers that like to start fires.
been tinkerin on my '71 for around 10 years now.
