Looking good! You're going to need a clutch fork like this:

The throwout bearing needs to have about .300-.400" freeplay when the clutch is engaged, which means you won't have anything keeping the pushrod from falling out of the pocket in the fork. This way, you can use a rod end / heim joint to connect it to the fork. Keep it up, hope to see you out with it this season!
