95 Cobra Transmission issues

My cousin has a 95 Cobra. Over the last few weeks he said he thought the clutch was going out. It died a few weeks ago, he was away from home and got stuck. He was able to put it in gear, start the car and get home in 4th gear. Now he can only get it in 1st, it will not go into any of the other gears. He said for a while it was going out slowly, then he took it to the track and I think that finished it off.

I'm hoping it is just the clutch. I am trying to help him out by getting him a new clutch kit. A guy from our local SVT club is going to help us put it in. The car is 100% stock (minus exhaust). I have searched and I think I found some answers to the questions below but still need some help (and verification)

• Input Spline count(10 or 26), looks like 10?
• Disc Diameter (10.5" ?) (10.500 in,10.400 in,8.875 in,11.000 in,10.000 in)
• Input Shaft Diameter 1 1/16th (1.062 in,1.125 in, 1.063 in)
• A part number of an example (like from summit or jegs)

I also plan to replace the throwout bearing, rear main seal (new or resurfaced flywheel).

Thanks

Thank you very much !

Just called him, he says he can put it in any of the gears and start it. He says if he puts it in first and tries to start it it grinds.
