    Use the Chrysler 3 jaw puller to remove stock damper. It's close quarters and still a pain. Keep puller torqued to the right as that's where the lands are.

    The tab to the right of the crank needs to be filed down (I removed half of the tab on the crank side). Do this before installing the pulley or you'll be removing it (much easier than old pulley).

    To install, just use old bolt with thin washer for a few turns, then install new bolt and torque down (torque specs on bolt review page).

    The belt was very tight, even with tensioner fully depressed. I had to put the belt halfway on the supercharger and turn the crank with a socket wrench to walk it on.
