I just bought a 92 YJ with a 6 cyl and automatic trans. The jeep has a small shackle lift and is missing it's rear driveshaft. The prior owner blew a U joint, and removed the driveshaft so he could drive it on a trailer. I need to purchase a new driveshaft (prior owner threw it away). Are the driveshafts the same for automatic and manual transmission YJ's? If there is a difference what makes them different?
