I have a 70 c-10. It as a 3.73 posi rear end out of a 71 suburban ( I think). But I have some questions. First is there any way to tell what fluid goes in it. And I know I will have to take the cover off the drain it but when I put a new gasket in will I need to put silicone to seal it and if so where.


thanks
