When i have my new flywheel and clutch put in, this would be the best time to have a quaife differential put in at the same time wouldn't it? It looks like it would help alot with traction when i get the powerworks installed later, since i dont have the traction control option anyway. Thanks.

Who is going to install it for you. How much?

yes, when you have the trans out for clutch/flywheel is the best time to do it because the trans has to be out of the car. it doesn't take very long to install the diff, I'd guess they'd charge you maybe an extra 2 hours or so.

my dad knows a mechanic, and old friend, he does good work, but not sure how much it would cost me. I know he would give me a read good price.
