Yeah, I think I'd do a non-Rubi LJ too. They look pretty sweet on 35's (and even better on 37's). I'm pretty sure I could build a set of JK axles to handle 37's without too much drama. They are almost as inexpensive in the Dana 30/Dana 44 combo as TJ axles are.I agree with the high speeds delimma with the 4:1 T case, will find myself in 4th gear while in 4 low quite often with the 5 speed MT.
If I was doing it over, I'd build a non-rubi LJ since their prices aren't crazy. Modify to properly fit 35s with lockers. I've never wheeled without them and I think I'd find out quickly how much I miss them.
