Yep, I did it last year or I should say I had All American Drive Services convert mine.. I tried to convert it myself and ended up wasting a lot of time and $$

Basically they converted the standard bravo to a bravo X.. I also had them go thru the entire drive while they were in there so new seals bearings etc. I discovered 2 things when trying to get the larger U-Joints on a standard bravo. 1. you can't get the spanner wrench over the larger U-joints and the wrench for the X and XR drives won't work with a standard bravo retainer ring. 2. The collar on the input yoke going into the drive is about 1/8 of an inch longer on the standard bravo than it is on a X or XR so when you put a standard bravo bearing pack on and start to tighten it the O-ring starts to bulge out before the nut is even tight. Look thru my forum I documented what all I did last year. Phil'R Up 2001 Baja 25 Outlaw
