I think summit has them in stock. I usually check their stock when we race at Cresson because... well... CMC car.

Going between T5 and TKO on mine is trans, shifter, bell housing, sometimes shimming the clutch pivot. You'll need a 26 spline clutch for the TKO600. My driveshaft and trans mount work for both, that may be different on an sn95.

I've had the T5z and the TKO in and out of the car several times this season.
