Ray -
Maybe the best idea would be to contact a place like Steer and
Gear or other place that specializes in rebuilding vintage steering assemblies.

Subject: Re: [Chrysler300] Power steering Fluid for D My 1957 Factory Service Manual advises to use "Type A" automatic transmission fluid in the power steering. That's the same as recommended for the transmission. However, that stuff is long ago unavailable, and Don Verity advised me to use "Type F" ATF in the original Torqueflite transmission he rebuilt for my 300C. Therefore, we put the same "Type F" fluid in the power steering reservoir (after sucking out all we could of whatever had been in there for at least the last 48 years since my father bought the car in 1968). Now the power steering seems to work just fine - doesn't squeak or leak. I think there's a strong chance that a modern, dedicated "power steering fluid" might not be compatible with all the soft goods in the system, including seals and hoses, possibly leading to significant leakage. Not only that, but the "new stuff" might not have the lubricity characteristics required for the metallurgy and clearances in the 57+ -year-old mechanism, possibly leading to aggravated wear and possible failure. It might be analogous to the situation with using modern low-zinc oils in the
engine, whereas the engines of the era were designed to use an oil with higher
concentrations of zinc and phosphorus, which was standard for the time
frame. Using the new low-zinc oils (mandated by the cursed EPA in 2007!)
can cause premature wear (and outright failure) of our good old flat-tappet
lifters and cams. Ray Melton Las Cruces, New Mexico 1957 Chrysler 300C convertible S/N
