Gonna be changin my clutch soon as it arrives just wonderin how much gear oil
do i need to buy to refill the tranny?

 

about 4.5 qts.

 

buy 5 quarts of redline and your set. Its pretty good stuff, there's better but its reasonable priced, and you really only have to change it a couple times during the life of the car. Barring any unforeseen rebuilds. Its about 8 bucks a quart, you can find it cheaper if ya look hard enough. Amsoil makes some nice stuff too. Silkolene is some quality lube as well. I suggest buying a differential filler hose, that or take a garden hose, its kind of a pain to fill out of the bottle.
