Please assist with ordering replacement parts for the attached pictures need left and right

I could not find a name on the part. USPAT4241.541 CANPAT350.432 this number was also on the main part 40471.

Here are some other numbers on the other parts - 20610, 20545, 30472 R.H., 30342R

Hope this helps. Apologize for how dirty the parts are, old windows.

I have additional pictures but could only attach 5

Thanks in advance

Anne 

Tom thank you so much for your help
