Using a grinder to lengthen the grooves is something that CAN be done. I have never done it but have read forum posts of folks who have. I can't say I'd do that myself.

Another option is to trim away (grind) the clutch disc splines. The clutch disc splines bind on the shaft when the clutch disc moves towards the tranny. By nipping away the corners of the clutch disc splines, it allows the clutch disc to slide away from the flywheel just a bit more. I also have never done this and can't say that I would, but it's been done and it works.

Lastly, you can swap the input shaft for a Jeep T5 shaft. The photo I posted earlier shows that the splines are cut longer along the shaft which allows the clutch disc to travel properly. the down side to this solution for YOU, is that you'd have to change your clutch disc to a 10 spline.
