hydraulic clutch in A body
My T5 converted '65 Valiant has an Annular T/O (Hyd.) bearing. The shims aren't for adjusting, they're spacers for rough placement. The unit has a threaded sleeve for fine adjustment. And you don't adjust them once you have the spacing correct, they're self-adjusting because the PP will only push them back so far and that's all the further that they move. So the adjustment that you do need to make only determines where in the pedal travel you want the feather point to be. After that there is no more adjusting necessary for the life of the clutch.
7/8" MC is
not correct. Most run a 5/8" MC, some use a 3/4" MC with really high pedal ratios.
Wilwood p/n 260-1333 is the pull type slave cylinder.
I can add some pics if there's interest.
