You don't quite have the correct measurements;)
The main body of the arm is 32mm as you describe,but where the bushes for the diff end mount,that mounting point is close to 50mm,so doesn't fit the early model diff housings.This increase in diameter is due to the way that the area for the bushes is increased for added support and strength.I reiterate that these arms are not your average lightweight mass produced replacement arms sold by other companies.The chassis end mounts will fit no problems.
I have been in discussion with Greg regarding the earlier narrow bushed arms as fitted to early Rangies and 110's,and threw some figures around,but this will require a complete new arm and bush setup,and not sure how much of a viable proposition this will be.I also have a vested interest in this ,as my 130 has early diff housings and narrow arms,and is just busting for a set to suit.
