The part I am looking for is very similar to the Truth Entrygard 90-031 except the short link is 3-3/4" long rather than 4-7/16 long as shown in the drawing.
Thanks for posting. Good eye. See our 39-156 (the opposite-handed version is the 39-155). This operator is identical to the 39-032 and 39-031, save for a 3-13/16" link arm. Take a look and let me know if you have further questions.
