B414 Clutch not engaging

[dctaz37]

I have the bolt out as it is easy to access from the inspection plate. It looked like it has been cracked for a while. I'm hoping this is the only problem. Everything else looks okay and the bearing isn't rusty.

The manual for the adjustment says, (6 7/8 from bottom of pedal to floor plate with tractors equipped with dual plate clutch, 5 13/16 for single plate. Pedal travel is 3/4" for dual plate or 1 7/8 for 11" or 7/8 for 10"). How do I figure out if it is single plate or dual and 11 or 10" ?

I've attached a pict of the broken bolt and the clutch.

Okay I replaced all 3 bolts. The other one was about to go, the head was worn off. I just need to adjust the clutch now as it engages pretty high on the pedal.
