OK so Dennis Carpenter has these for F500-600 trucks for 75 bucks. I put one on and it won't go on far enough to line up with the water pump pulley. Shy about 1/4". IR impact wrench and regulator both turned up to loud!!! Is this to be expected? If so should I make a shim for the w/pump pulley outa some 1/4 inch stock I have on hand? Would that possibly cause a balance problem?
I'm a bit confused because my shop manual for the '59 Ford trucks says the 500-600 may or may not have a HD engine as opposed to a MD. Would there be a difference here? Am I making a mountain out of a mole hill?
