alternator pully swap

The last thing about your proposed pulley is that even if it does fit properly, and might not, it does not have the front collar for the puller. You will never get it back off the shaft "if the time comes" I don't know "who" but there are (Moroso?? etc) who make large Mopar pulleys

Also, it looks wider and flat bottomed? Might be the photo? If the belt bottoms out in the pulley it will slip.

Check with your local "parts stores" O'Reallys and others. Some of these outfits have the proper puller you can borrow. "By any other name" these pullers are also used on power steering pumps. You MUST use the center "knub" or collar to pull that without damage

There are several designs, all work on that center collar
