Pella Window crank and Plastic cover/tray

I am searching for a window crank and cover/tray that it sits in, to replace on that is broken. The plastic tray pops out of the wood window framing and the crank is missing a small screw on the side. The handle comes out of the tray every time you open/close the window. The window is a Pella window circa 2001. The only number marking on these two separate parts is "77BJ".
Thank you.

The photos of the plastic tray show that part of the clip that holds the tray into place in the wooden window frame, is broken. The 2nd photo shows the hole where the small screw is missing. Without the screw, the handle comes off when cranking
