I am converting an SST to a Drenth sequential gearbox with pneumatic paddle shifter controls for racing and rallying and I need some advice.

Do you know whether or not the Left Hand Drive Shaft on an SST is the same as that on a GSR or is the output spline different. We seem to have a problem and I need to find a solution quickly.

If these drive shafts are not interchangeable, does anyone have a Left hand drive shaft for a GSR that I could buy.

 

You could look on e-bay and hit up a lot of forums to see if someone is selling one. Or you could go straight to an aftermarket unit like Driveshaft Shop's or even a carbon fiber one.

If you're going through all the trouble to switch out the transmission to a racing sequential you can go all the way and get a solid aftermarket driveshaft.
