Spare Motors...gotta have a couple.
I ordered mine from Tascaparts.com just to see if the order would go through a few months ago when I found the new part number. It worked and they were shipped from Mopar Performance.
Actually they shipped from Michigan to Tasca on the east coast and then sent to me back in Michigan. I guess they did not drop ship. Lol.
I don’t think anybody was notified of the drastic part number change. Not superseded, just changed, making old number no longer available. Summit could order them, being a Mopar Performance dealer, but they don’t know to list the new number.
