thats awesome it looks way good i have always been a mj fan i give you mad props for the wrench time

 

[Revenant]

That is way cool...mostly because we don't see 'em everyday. Nevertheless, way cool!

I love the front clip swap! good job; now shoot some paint and match it all up

 

[DaveB]

Looks great. Did you by chance keep the old fuel line from the filter to the rear fuel rail connector ? My son's MJ needs one and I'm having trouble finding one. If you have it could you send me a PM and let me know how much would you want for it ?

I'll check Dave. The front clip and fenders swap was the easy part, it was all the other stuff that drove me nuts. Paint is in the works, I just haven't had the time to finish getting the cab and doors to white primer like the bed

 

[XJumpmaster]

Very Nice!

 

[dStuck]

for the front clip is it pretty much a bolt on job? and will it work on a 90 XJ?

 

[Thursty]

Looks awsome. Post some pics when its all painted I'd love to see them.

how bad was the motor swap? was it originally a 4cyl? i have a 88 2wd 4cyl 5spd that i was going to swap to 4wd but i am considering getting an xj 4.0/aw4/231 and swapping all of it. i figured it should be pretty straightforward since i will have everything in working condition and it just needs to be swapped, but any insight would be great. thanks
i have a thread in gen 4x4 if you want to reply there or whatever.

The motor swap wasn't too terribly bad. It was originally a 4.0, but I wanted 50k versus 175. But it still seemed to drive good. I think the only problem you'll run into is if its a newer 4.0. We swapped the whole drivetrain, but also swapped the entire dash and wiring harness, so that made the engine swap a lot easier.
