Hydraulic Clutch in a 66 Barracuda

So, I've decided to put a hydraulic clutch in the Barracuda. The main reason is that I've never really gotten the clutch linkage working right since the conversion to 4-speed. This is likely because I had to customize the z-bar since these cars came with a smaller bell-housing than the one I used. So the angles are probably a bit wrong, even though I got everything to line up. The required pressure to disengage the clutch seems way over the top, and there seems to be way more travel than there should be.

Besides, I have to pull the trans anyway to fix the leaks, and hopefully track down this vibration at highway speeds (input shaft?). Plus, there's that stripped bolt hole in the bellhousing which i need to put a helicoil into... not to mention that i cooked my throwout bearing by adjusting my linkage wrong (I think).
