I just noticed (looked at belt set up diagram in manual) that I should have a dual grooved water pump pulley on my 350 w/ PS (no air). Instead there is a one groove pulley which results in the PS belt only running thru the PS pulley and crankshaft pulley (fan/alt belt runs through crankshaft pulley, water pump pulley and alt). Bought the car this way approx 3 years ago and steering seems to work just fine. Other than not being "correct", any harm in this? Thanks! Bernie
