Lugnutz is just changing the input shaft.
This means you don't need an adapter plate or you don't have to shorten the input shaft and the collar that the throwout bearing rides on.
The Jeep shaft will need to be shortened. The S10 and Jeep shafts measure about 9.25", which is about 1/2" too long. The V8 Camaro shaft measures 8.75" and is the correct length. A Camaro shaft has 24 gear teeth and will not swap into an S10. That would be the best solution of all, but it doesn't work.
The original S10 shaft sleeve will also need to be trimmed back so that the Jeep splines are fully exposed. The photo below shows a Camaro sleeve (shorter than the S10 sleeve) which is about the right size. Just trim off enough of the S10 sleeve so the end of the sleeve won't contact the pressure plate fingers. The Camaro sleeve is about 2 + 5/8". However, trimming the S10 back to just a bit under 3" is probably good enough.
V8 Camaro shaft = 8.75" next to S10 shaft = 9.25" Jeep and S10 shafts both = 9.25" Mark and cut Jeep shaft at 8.75" - make sure to chamfer the end.
