Had to bend down the retaining tabs (on the drum) a little to allow the paddle to slide on. Placed the paddle with the tabs in all of the grooved slots, pushing down with one hand, I used my palm to firmly push/tap it into its locked position.
I purchased new vane screws (Part #: AP2106572 "131302800") and used a Phillips driver to screw them in (one each paddle).
It's that simple!
