Crank mechanisms needed, two types (right and left?)

I have attached two pictures with measurements and cast-in numbers, I need two mechanisms with the "40471" number and one with the "L31538A" number. Please let me know if you need more information

Good morning! Check out our 39-031 & 39-032 and see if either of these could work for you.
