Crank out window sliding part top and bottom

This part is from a 2001 year Crestline crank out window. It is the part at top and bottom that slides in the window frame. The item had a black plastic part with a lip that slides in the window slot. I didn't see any part numbers or words on them. I think the top and bottom parts are similar or identical with an arm with a clip to engage the pin in window frame. The plastic part broke while trying to slide into the slot. Both the top and bottom pieces are broken.
