Inliners,
I can't take any credit for this idea. I do think it needs to be talked about as an option that is better than the adapter plate.
I recently proved to myself that you can put a Jeep T5 input shaft on an S10 T5 transmission and make it better plus save money by continuing to use your 10 spline clutch kit for an older Chevy car or truck.
The Jeep input shaft is from a T5, has 10 splines and 21 gear teeth. The splines are cut along the length of the shaft more than the S10 shaft. That way I won't need any adapter plate. The Jeep shaft is thicker (stronger).
I plan to post a DIY thread later.
The Jeep shaft still needs 1/2" cut from the tip so it will fit a V8 bell housing, but that is no problem.
Below is a photo after installing the Jeep shaft. I have installed a shorter (Camaro) bearing sleeve but you can just cut the S10 shorter. That is my 10 spline clutch disc (on backwards, LOL!!!) I need to cut the tip off at the tape and chamfer the edge. The splines are long enough that I do not need an adapter plate.
