I bought a 81 turbo zx r200 with cv shafts for $100.00 to replace a r180 in my 240z. The JTR adapter that works on the r180 will not fit on the r200 diff. The pinion spline is larger on the r200, and the flange pilot is 2 inches instead of 2.25 inches on the r180. I did a search in drivetrain area without finding any help. Anyone know of an adapter that will work? Or what about machining the JTR adapter to fit?
Thanks for your help
