When upgrading to the newer tensioner style, the Mopar service kit includes a new plastic belt cover due to the new tensioner arrangement differences. You may be able to modify your old cover to work with the new style.
Aftermarket tensioners may still be available in the old style arrangement. Mopar no longer carries the old style.
