I'm NEARLY done w/ my 4.0 V8 swap into my 530iT --- which rear axles do I need to use with the 540's big 2.93 rear end?

I thought I was supposed to use the 540's axles --- BUT, the wheel end of the axles (versus the diff end of the axles) does NOT appear to fit inside the housing the holds the wheel bearing --- does that make sense?!

Do I have to undo the locking collars and take the whole setup apart, etc? Please say "NO!"......

I'm on a tight schedule now - anyone have any info?

Thanks very much!
