well the only thing i have on the crank is the alt, and i truthfully don't know if the alt pulley is press on or bolt on. haven't been out to look. I also didn't see a larger mopar alt pulley being marketed for chryslers. Just ones that say Gm/Ford...so that would lead to be reaming out the bore to fit the mopar. At the end of the day i found the moroso pulley for $50, and i know that it's only bolted on...so seems easier at the end of the day.
