Outer Limits 4x4 Board

ok, so i've got the a-frame about to go in the back of the lux. also have h55f box and transfer with offset output shaft.
was going to use an ifs rear housing and axles. just to gain the width.
i beleive a bundy rear diff has an offset center and will accept the lux center. is it as wide as a ifs lux rear housing??? if it is, that would be perfect cos i would have better tailshaft anglesie not having to cross from centered diff to offset transfer.

why not use the offset wide as 80 or 60 rear end ?

i bought an air locker and new 4.88 gearset about 2 months ago. i was hoping to reuse that. i just want something wide that my diff center will bolt into.is prado offset??? wide??? lux center compatible??? expensive???
i can get an ifs rear diff minus the center for $400
