Rear Diff fluid
Hello, I have a 79 450SLC 5.0. The rear diff is leaking, is there a gasket? or do I use silicone? Also, what is the correct fluid? How do I know if I have a LSD?

Gasket, but I do not have the part # at hand. Silicone won't patch anything like this. If I recall correctly, the first 107's to have limited slip were the 560SL's 1986-89.

Ive checked with the dealer, there's no gasket on the 450's, I think the 560's had a gasket

Ok, so I confirmed that I do not have the LSD. Now, whats the best fluid to use? 75w90, 85w90? Do I need GL4 or GL5 spec? Its so confusing! and everywhere I search I get a different answer. The dealer doesnt have a good answer either. Classic center has not gotten back to me yet. Any advice?
