I need to replace two cranks, one left opening, one right. Do you all have e these parts?
The only text I have to go on for this one is that the arms read: 31876 and 41011, and the main body just has a date/time (10/05/01 05:15) and "Made in the U.S.A." Printed on the underside.
Thanks for looking into this.

Hello,
Your operator resembles the 39-253RB and 39-253LB operators, which both use the 39-529 track slider. Review the specifications below and look over the related items shown on this page to confirm they match your original hardware. These operators use the 39-376 and 39-375 handle with cover kits. Thanks for posting!
