1953 Mercury Power steering Cylinder

[Sunnybob]

Hi Folks,
I'm adding power steering to my 1953 Monterey and I have found almost all original parts. The power cylinder has small leak so I was thinking to buy another one. Rockauto has two types.


Lares 30 has external tube, like mine, but is only Remanufactured and the core is a problem for me as I live in Italy. The other one, lares 10031 is new and cheaper.


Has anyone tried swapping them and know if they are more or less interchangeable?


Thank you.
