Ha Ha, I've had my trans out so many times (clutch's mostly) I gave up "sealing" the trans tunnel. I just screw it back in, step back and say, "Screw it."
Dane, if you drive like I do, you'll need a new clutch again shortly!
I just bought a new extra heavy duty killer clutch to go with the new TKO from Blykins. I THOUGHT my old clutch was still OK until I put some slicks on the car recently. Sure enough, my clutch was actually slipping on a hard launch, I was quite surprised it was already time AGAIN for another clutch!
