What 833 gear/diff lube?

hey there:

clifft - i got one of pat paulsen's "dollar bills" with his face instead of washington's - without getting too political here, if paulsen was running today i might consider voting for him over some or our other choices recently.. as to "old car parts and stuff" ... i generally go to a local NAPA store that has never been remoulded and has a "parts counter" that looks like someone rebuilt a cummings on it. the guys there look like the only way they will ever leave that job is on a strecher...

mr. demon 340 ....
could you give me a little more information on the products you're suggesting ... like who makes these products - GL-4? jamie parsons fluid? "red line MTL?"
i think pensoil or quaker state sells 85/140 gear oil here in pittsburgh but i'm not sure of the additive - will mopar "sure-track" additive work in old posi-trac diffs?

thanks for all your info..
