The closest match for length of link arm that i can find on your site is 2-3/16. i have measured twice and mine is actually 2- 5/16 to 2-3/8 (not sure if being short will work). I located closest operator that I could find on your site (met most of criteria) and listed my measurements (included drawings). Note: 2 holes on top and bottom of operator; (facing front of unit) top left hole lines up with bottom right hole
