What 833 gear/diff lube?

Redline MTL (manual Trand Lube) for the 833.
For the Diff, Redline has several gear lubes, most already have the limited slip additive in the lube. The 75w-140 Light Weight Shock Proof has been working good in my 8-3/4" diff. in my 11 second #4,100 lb Charger.
I use the regular redline gear oils in my other cars and trucks.
