Thanks Jeff,

I did a bit of ringing around and found out the standard clutch behind the Corvette LS1 uses a 26 spline input shaft. Hays make a clutch and flywheel setup to suit the coarse spline box to the late Chev but that will cost me about AU$1700. That makes a AU$3500 T56 gearbox look a lot more attractive since it'll bolt straight up. Also if I use the 4 speed I'll probably need to change my rear end ratio which is currently 3.45/1. So I figure I'll save my money and buy the 6 speed box or a Tremec and use the original Corvette clutch.

Cheers
