So I've been told its a technicle job to swap just the gears in my stock rears. Now I'm wandering about buying a donor with a better stock gearing. I have a 1993 Cherokee 4.0 five speed manual. With stock 307 gears. I'd like to move to 410 or close to. But I need to know what all I need to be sure exists on a donor. Ie.... yoke, drive shafts, brake components etc..... also are the grand Cherokee rears compatable. Thanks for all advice / help
