I'm getting ready to build my P/S / Hydroboost lines, and in preparation I was reading through some old power steering threads. This one in particular caught my eye: http://forums.corvetteforum.com/show....php?t=1611420

power steering flow settings:
1967-1969 1.75 gal/min
1970-1973 1.60 gal/min
1974-1981 2.90 gal/min
1982 1.9 gal/min

Is the flow control valve in the output port a direct replacement among those years? Could I drop the 67-69, 70-73 or 82 valve directly in my 77's pump? Where could I find one?

All of the fittings will interchange into the pump. But be aware that starting in 1980 the fittings were changed to 16x1.5mm o-ring connections and require a pressure hose with the correct metric end at the pump.

Thanks, Jim. Do you have any idea where the valves can be obtained? I know that you've said that most rebuilt pumps require the re-use of the valve from the old pump.
