Parts Help Needed (Shower and Light Cover)

[dparker999]

We have a 2022 Heartland North Trail 21RBSS. I need help finding two parts. The first is that the wheels snapped off one of the top shower door rollers so I need to order that replacement (photos attached). The second is the lens cover for the reading light above the bed (the one you almost hit (or do in this case) when you raise your head getting out of bed.

Any assistance would be greatly appreciated!
