B/W type 75 I think out of a VL commodore same as skyline, 28 spline 4.1 with true trac custom shafts and BA brakes with Subaru twin pot callipers. But it was $$$$$$ Supply and fitted a little over 6K could have done it cheaper but did not have the time and need it on the road asap to keep project moving forward, had to work some overtime to pay for it. Work done by Diff Trans south Windsor.
