Have a LSD rear diff out of the n/a model that came with them, has the 4.3 R&P (GTUs?). Its a clutch type LSD, correct?

Question is, what fluid is recommended for this diff? Getting ready to install and gonna put fresh fluid in beforehand.

What fluid and how many qts?

thnx in advance

you need to make sure it as additives for LSD. So look on the bottle to ensure its says "safe for Limited Slip" or something along those lines.
