Default Front snd rear diffs

I'm going to be changing my front and rear diff fluids here soon. I know in the back with the 3.55ls I'm going to run 80w90 but what is everyone's preference on brand? And also what's the best way to go about the front as far as changing it and what oil to put in it? Thanks

I put Lucas 80w90 and a few ounces of the friction modifier in my rear diff. (3.55ls) and haven't had the first problem
