So I've decided to ditch the clutch fork and slave cylinder on my conversion kit because they interfere with the catalytic converter's position (can't even bolt up the bellhousing without a slave on, it's that bad. gonna have to grind off the mount point for the slave cylinder sadly) and I'll be going for a hydraulic howe setup. I've already ordered a toyota style round face release bearing for it, but I'm kind of curious about something.. exactly how much space do I need between the bearing fully retracted, and the fingers of the pressure plate? Sorry if this is a dumb question but this is my first venture into hydraulic throwout bearings and I want to do it right

Also I've heard alot of mixed opinions on the howe bearing.. should I consider another option in the future or is all the negativity coming from people who set it up incorrectly leading to the piston overextending and leaking?

EDIT: I should mention that I am using a 5/8 master cylinder with what I believe is a 1" stroke and I just found specifics on my TOB, it states that I should have 1/16" clearance, should I put it a bit closer or will the 5/8 master cylinder provide enough travel? I know there's plenty of people who have used a howe TOB on their sc400 manual swaps so I'm sure someone can provide some input on this.
