One has the shifter forward, with a 10 spline input shaft, the other has the shifter towards the rear with a 27 spline shaft. I believe the 27 spline will not work with our trucks, correct?

It would be 14 spline not 10. No T5 has a 10 spline shaft. That's why you need the clutch kit for an Astrovan. It is a 11 inch clutch with 14 spline. Much better than the 9 1/8 inch disc in the S10
