Here's some install kits

http://www.ddperformance.com/T56 Kits.htm


As you can see there is a ton of variations of the t56. Maybe call up d&d and see what they have to say.
 
will the splines even be the same? No, 26 spline input (need a new clutch unless you have a TKO already installed) and 30 spline output

drive shaft length be an issue? Yes, you need a 30 spline driveshaft and it is shorter than stock

what clutch and pressure plate do i get? I would recommend the McLeod street twin set up. It comes with an aluminum flywheel, dual clutches and pressure plate - $750.00. That will be the last clutch setup you buy for a while. I'm making 560hp and 550lb-ft at the wheels.
