I ended up using a hydraulic throw out bearing from American Drivetrain with a Center force dual friction clutch and Lakewood scatter shield. I tried to modify the Z bar but I still interfered with my TTI headers and did not work smoothly. I did have to machine about 0.090 of of the hydraulic throw out bearing to get the proper air gap at the clutch. The pedal is firm but not hard and the a833 shifts smoothly. Just note the front suspension is stock k frame and torsion bars
