That truck was available with a small block V8 from the factory. Why not use the OEM mounts instead of trying to reinvent the wheel? It had a hydraulic clutch setup, with a bellhousing with the window for the throwout fork on the passenger's side of the vehicle. That bellhousing is a little difficult to find, but not impossible. It will bolt onto the same crossmsmber in the firewall area where the current 6 cylinder bell mounts and it will solve your angle and height problems. I believe there was a bracket in the front that moved the horse shoe mount back to meet the shorter V8 engine, or there was a different horse shoe mount for the V8.
