On my '72 C50 with 350 SBC and factory power steering, there are NO hydraulic hose connections to the steering sector (box), the hoses run from the PS pump to a hydraulic ram, the ram is bolted to the axle on one end and the tie rod on the other. This system was used on Corvettes up to 1966 that I know of. I wonder if the rebuild kit for the Corvette ram would work for the C50? Ecklers' Corvettes used to sell rebuild kits for them, about $40. I also have a '67 GMC V5500 (same as a C50) that is not power steering, it appears to have the same steering sector as the '72 with power steering, fwiw.
The power steering pump on my '72 with 350 SBC has the power steering located under the alternator, with a single sheave pulley on the pump. The pump also does not have a reservoir on the pump, the reservoir is mounted on the core support behind the drivers side headlight, it connects to the pump via a ~1" rubber hose. The power steering pump has a pressure and return line going down to a hydraulic ram which has a spool valve the spool valve is operated by the regular tie rod, it senses the tie rod movement and directs hydraulic pressure to the ram. the ram is connected to the tie rod on one end and to the front axle beam on the other. My power steering ram started leaking so I took the PS pump belt off, I am looking for a rebuild kit for the PS ram. I was told an AC DELCO 36-351650 was correct, but applications table list Ford and Mercury products only. Anyone out there rebuilt one of these ram systems? A part number for the kit would be greatly appreciated!
Good luck!
