I can appreciate the desire to have a remote PS reservoir.
On my 69 427 with PS and AC the Alternator sits directly above the Saginaw PS pump because the AC compressor and smog pump occupy the passengers side.
I cannot take the cap off the PS pump to check the fluid level - from the left side of the car. There is no way I can contort my arm, elbow and wrist. I have to do it from the right side of the car. It's a PIA no matter what.
I wish George Jonas's (RIP) of SSBC (RIP) was still making the control valves and cylinders - I never has a customer with a leak. Get this - if I recall they were $100 each for 25 - no mix or match - 25 valves or 25 cylinders. Well worth it.
Today I don't even resell either. Too much leakers. Negative cash flow,
