Well, cars used the stamped steel pulleys we posted above which are a different offset. Reason you use this PS pulley is for the odd offset of the AC system and or the cast iron crank pulleys offset for trucks only. If you spin the PS pulley you can gently tap on it with a rubber mallet and get it straighter . Ive done that before. Heres a couple pictures of the car pulleys I used in my 66 GMC Suburban project. I used the later 67-72 era PS pump and brackets as I wasn't going 100% stock. You can see how close together the crank pulleys are. The center crank groove is for the AIR but Im using car type AC brackets on this one.
