hydraulic clutch without a kit

since I have to pull the drivetrain out of my 70 duster due to a fragged clutch, I figure now is the perfect time to convert to hydraulic actuation.

im planning on a pull style 3/4 diameter slave, and would like to match with a wildwood remote reservoir 3/4 master. ideally, id like to use the factory holes in the firewall.

has anyone done this, and if so, how? id really like to avoid bespoke parts and 600 price tags in any way realistically possible
