I have the 55/56 PS filter in stock. Let me know if you want one.

  Interesting discussion. Auto manufacturers would not be expected to add an
  expensive item like a power steering fluid cooler without good reason,
even
  if only government mandate. Anyone aware of problems with earlier power
  steering systems associated with hot fluid? I can't imagine power steering
  fluid getting any hotter than engine oil. But it is a relatively small
  volume that has energy continuously added to it by the pump. If there was
  and is a serious safety or performance problem that can be cured with a
  cooler, perhaps we should consider retrofitting our older 300's and other
  vehicles.

  I rather like Chrysler's idea of placing the power steering pump on the
back
  end of the generator on the '55-'56 300's. Fewer belts and pulleys and
easy
  to access. Any problems to look forward to with that arrangement? I know
  there is a rubber shock absorber piece that connects the pump to the
  generator shaft. Is that likely to "go" someday? Any source for those?

  I recently had to drain the power steering fluid reservoir on our 1955
C300
  in order to get the LH rocker arm cover off and found a lot of black
sludge
  in the bottom of the reservoir--so perhaps the p/s fluid is
  deteriorating--or the rubber hoses in the system.

  Is there a known source for the filter that goes in the '55-'56 p/s
  reservoir?

  My '65 300 has what appears to be a factory installed power steering
cooler,
  I believe it was checked on the build sheet and I have seen another '65
  Chrysler with the exact same cooler. Works well, after driving well over
400
  miles on a hot day (mostly highway though) the fluid was just warm. It's
on
  the return side so there isn't really any pressure or leaks as long as
  you're using the correct hose.

  Just wondering if anyone else has done this and if it's necessary.
Shouldn't

  the seals, etc. in the pump be able to withstand the heat that is
  transferred from the engine ? Additionally, my concern would be the
  introduction of additional hoses into the equation, which can leak or
split.
