all you have to do to remove crank pulley is put the car in gear with ebrake on ....get a breaker bar or air gun if available...turn counterclock wise to loosen bolt....now when installing put some oil of some sort on the pulley..align it on the crank...not get a bearing race set if available its a tool that installs seals..will work to mount pulley on crank...once ;you o got it on crank use the bolt to torque it down snug...it should stop once its flush on crank...dont fight it after that...because if you break the head offf the bolt then u will be screwed
wesellcarparts does not carry them anymore, all they sell is the ralco RZ pulleys. which is 2 pulley set. I think you have to buy them directly from NSTs website. They are more expensive cuz your buying them directly from the company, Retail prices!
