Hello, i am looking to find a replacement part, either the full assembly or the splined gear for the transmission differential. We have tried nearly every one in the states and have now been looking in Europe. No luck. Has any one had to replace this part and how did you find it. Any assistance would be helpful. Apparently it is a quite a unique tranny and part. The gear is 61 spline, four inspection window and 3 identification grooves. Thank you
