I am trying to fix a leak on the front output of a 85 Toyota Truck tcase. According to the dealership diagrams (not much help, behind the flange there is the metal retainer with the felt and then the seal with two arrows on it. When I pulled mine apart there was a metal seal (no felt) and then the seal with two arrows. I think somebody sourced a seal that fit instead of using the felted one, but just want to make sure I have the right parts. Thanks
