I have both, a CJ7 and CJ8. Just about every thing on the 7 can be used on the 8, and vice-versa. Main differences through the years would be in the drivetrain - the engine/trans options and the axle width. The last year of the CJ's (86) could have the wide track D44 rear. The difference in the CJ8 is the lenght of the frame(extra body mounts also), the rear fenders flares, the tub(door pin back), the roll bar, and maybe a few more I can't think of right now. The grill, front fenders, seats, lights, blah blah - same - you will have to be more specific. Try here, www.cj-8.com, for more information on the Scramblers. Feel free to pm me if you have any questions, Rich
