Any recommendations for diff and tranny fluid, **besides redline**? can't find it around here, and i wanna change fluids tommorow. I think i might wanna shy away from synthentic, as i don't really know the history of the tranny, and don't really want it to start leaking. the diff was apparantly rebuilt in the early 90's, but has probably only had 500-1000 miles put on it since then. either way, seals are still 10 years old.
