Ok guys I have an ls1 in my rx-7 (FC) and have everything hooked up and ready to go. The shifter was a pain in the *** but I got it to work. I also had a driveshaft made by a shop with the triangle flange fitting and all.

I am also using the CTS-v clutch, pressure plate and flywheel.

My only issue is do I have to put an ls6 pilot bushing instead of the ls1 pilot bearing I put in there. Everything seemed to mate up just fine and I am about ready to put the car on the ground and take it for a spin. Your thoughts would be appreciated.

 

I might have found my own answer. Dammit. Looks like I am going to have to pull that ls1 pilot bearing out and put the big one in there since the tranny is from a CTS-v. Any independent confirmation would be great. Thanks folks-

Derek

Yes, the CTS-v T56 input shaft is 1/2" shorter than the Fbody T56.
