I haven’t ran a 4BT in a CJ yet, but I have been around jeeps for many years.
I have broken U-joints on the Dana 30 front (in good shape) with 33's running a 258 I-6.
Doubt the Dana 30 up front would live long with off-road use. The AMC 20 in the back might be OK with trussing and flanged axle shaft swap.
Better yet is to find a front and rear Dana 44's from a Wagoneer and swap them in. (matching ratios and only a couple inches wider)
Some claim you need, Dana 60's but I doubt everyone needs them off-road.
T-18 and Dana 300 should be just fine...
4BT in a CJ-5 that would be fun...
