alright thank yall very much.

75W90 GL-5 Gear Oil
Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks, and racing vehicles
Contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763

This stuff goes in the Ralliarts Rear Differential.

The OEM DIA-Queen stuff is SAE90 with LSD additives.
I just use Valvoline conventional 80w90 and I have no problems.
