Outer Limits 4x4 Board

I have read every thread on here and there all about the 4.2 which I have done.......

Who has done an RB30 with the 300ZX gearbox?

Are they as heavy? and any special tricks to getting them out?

Just doing a clutch swap which is not the bit I'm worried about more so the removal/refitting anything I should know?

they're not much lighter. to remove and refit they are the same process as the 4.2 boxes, just one thing to watch, if you remove the transfer, drain the oil out of the gearbox first as the front of the transfer seals the back of the gearbox. i found out the hard way
