Nv3500 throw out bearing

[Rcj1]

I have a 64 chevy I installed a nv3500 with a hydraulic throw out bearing. Works great. I have a second one with an external slave cylinder how can I convert it to a hydraulic throw out bearing.

You would need to do a lot of modification since the bellhousing is integral. If the front bearing retainer is not interchangeable (not sure if they are) then it would be basically impossible. Easier to just get a 96-up version.
