diff lube

I have a crysler 8.25 with a trak lock LSD that I'm about to install under my heep.

What lube should I fill it with?
What lube should I fill the front d-30 with?

Thanks

I used valvoline synth blend 75 140 for the rear + the bottle of the additive that the dealer sells (for the lsd). And I used the 75-90 plain valvoline (or 75 140 synth blend when I ran out of the 75 90) in the front.
