Something wrong with that Fuzz?
OP, unless there is something wrong with the Rubi I suggest you just use it and not bother with the swap. Seems like way more trouble than it is worth.
Swapping the axles is a simple matter of unbolting from the Rubi and bolting onto the 4banger, but the engine swap is a completely different matter. I'm no expert, but there are a lot of differences not only between 4 cyl and 6 cyl models, but also between early and late model TJs. It could be done, but in my opinion the amount of work required would not be worth it, especially if there is nothing wrong with the Rubicon you would be neutering.
