Yes i am talking about the gasket under the rear tail house shaft housing....he showed me the gasket he installed ..he told me he is use to glides with after market tail house shaft and isntalled that gasket thinking it shouldn't affect anything...but i would say it does affect something...i was looking at the stock gasket and the one he installed and there is alot of diffrence as far as holes and placement......the tranny is out of the car and he has it now......but he hasn't looked at it yet........so i am curious on what the problems could be that is why i am asking you fellows
