Hi. We have a 72 lhd DJ5. No idea on the miles. There is a parts supplier at Postaljeepparts.com that has some good data on drive train issues. Mainly they say get one from the years that have mopar trannys & 232 engine or 258. If you only want the body then it really wont matter on that part. Sounds like they mostly all have same front and rear axles. D44 in back with Limited slip. you cant use autozone to order parts as they think DJ5 is a CJ5 and things liek brakes are not the same. DJ 5 was built by AMGeneral not Jeep so although they look the same they are not really the same. Steerign is armstrong on at least most of early ones so it is slow. If it needs a new sector think really hard about changing to power steering not that you need it but the ratio is a lot quicker which will help a lot driving at times. Ours had the BW t34 or something that died almost as soon as we bought the jeep. I replaced it with an AX15 manual. 97 2wd Cheorkee crankshaft back bolt in with custom trans crossmember and drive shaft. It is a lot of fun and if you can keep your foot out of it is getting better than 20 mpg in town. 72 is as basic primitive systems as you can find so it is easy to work on and understand. These were made a long time so you could get one with a lot of miles so plan on bushings, tierod ends, kingpins, carb oh, and on and on. Have fun.
