Hi Stuart...I'm confused again!(Easily done!)
The Speedway item i've been advised to use is shown fitting a Saginaw self contained unit.
Yet the self same item is shown in the Sachse link as the one for the GM type II stand alone pump.
What gives...do they use the same part? I've just ordered the Speedway one and i'll be pretty P'd off if it's the wrong one!(shipping costs!)
And BTW what's the difference with the RBS 1R600 Power steering valve?
What do I actually need to cure the problem? Is it a pressure or flow rate thing?
Thanks Jock headscratch
