Clutch help

[bad 71 chevy]

That was another question what is the accurate gap needed or is just mock it tell it works kind of thing. All help is appreciated thanks I have searched tell my eye have bleed still don't have a good answer, I have the og t56 tob just not sure if I need to order a new slave and line or reuse the current setup from the nv3500.

Thanks all for any and all guidance, the builds I have seen all go from auto to manual or manual with old clutch set up, have found none that have progress like mine and don't really want to spend 200$ if I don't have to..

Thanks again
