Tremec in a 66 c10

[truckin66]

Im installing a tremec tko in a 66 c10 to replace the super t10. I used the stock cast bellhousing and also made a crossmember for the tailshaft. Im considering going with a 621 car bellhousing and removing the stock bellhousing crossmember to make it easier to service clutch parts. It was a pain taking this apart. I orginally installed the clutch kit and bellhousing on the motor before i installed the motor. What clutch fork and link rod would i need. Will the stock cast fork work with the aluminum bells? Im open to other ideas too.
