what kind of tranny and diff fluids are you guys using. figuered i would chage them out while im wrenching on my car. thinking royal purple, (thats the oil i use)
When I change out the 331 gears over to (most likely) 373s I will go with the Royal Purple. Then again, every time I say 373s, what I really want is 410s!!!!!!!!!!! Damn decisions!!!!
