Why would you want to do that? Doesn't seem like that would be advantageous...........I'm coverting to Hydro because I have a hydro tranny.

As far as converting the cable trans to hydro, no real idea as I don't think it could be done at the trans very well. Nothing really in place for a fluid push to release via a fulcrum since it is set up with a cable pull on a pivot to release.

I'm not sure why, but here's a couple of possible routes I would look into...you'll be doing some amount of custom machining and fabrication with that gearbox and the pedals in a 1/3g. There are bolt-in conversion options for everything 4G and newer to look at for reference.
I would start with a Tilton hydraulic throw out bearing conversion kit for a B- or D- series compatible tranny, measure, measure, measure and machine an appropriate adaptor to bolt the tilton bearing into onto your tranny case, convert your clutch pedal to hydro set up of your choice. I'm pretty sure you have to use a tilton flywheel and clutch with their hydro bearing.... So your probably about $3K into this project in parts alone.
OR
a crazier idea I had.... hush racing makes a pull-type master cylinder conversion for B/D trannys that could possibly be mounted vertically to a cable tranny (???) to actuate the release arm like the stock cable, the pedals would still be converted to a hydro master cylinder but this would allow use of oem-type clutch and flywheel combos w full hydro action.... yeah! full! custom! smooth! hydro! action!!!
but seriously, why?

I've seen a vertically mounted slave cylinder on a B series cable box. The car was the hydro del sol, and they'd replaced the gearbox with a cable version. So they replaced the cable pull-up with a hydro push up, mounted on a bracket bolted to the existing bolts on the box. Worked ok, and solved that problem.
