UPDATE:
...since I have easy access to the UCA's, power steering gear and M/C and brake booster, I decided to start tackling their replacement with the genII parts I have been wanting/needing to replace them with.
Already have the genII brakes/rotors up front...

genII components:

old leaky m/c and booster:

new booster(doesn't have threads for the check valve but it screws in pretty snugly, hope it's not an issue):

got both UCA's off without having to lift the body, which is good, just have to get the new ones in.
old one attached:

removed:

still need to remove this leaky original and customize genII gear mounting hole to fit:

Once I get the power steering gear off, I'm going to de-grease everything visible and paint it up with a product I used on the rear of the frame called Chassis Saver which has held up very well since the genII rear end swap.
