Anybody have any advice on power steering control valve? (1966 Polara 318) I removed the one on the car because I had a leak where it meets the gearbox. I figured all it needed was new O rings. But when I removed it I saw that the small spring doesn't seem to be in there properly (partially obstructs the hole where the fluid is supposed to come through). I took it apart, there's a large spring, the piston and the small spring. Any advice on how these three pieces are supposed go in and align in the fitting?
