Mine is very similar to 39-090. It's truth brand. It's 5 inch. On mine the small bar is 3". Will that be a problem?

Agreed: 39-089 and 39-090 are our closest (and only) replacement options .

Concerning the different sized link arms, I believe you'll need to remove the new arm and swap it out for the old arm. You'll start by drilling out the rivets on both the new arm and the old arm, then installing the old arm on the new operator with our 62-014 rivet. Do you think you can manage that? It's really hard to replace some of these old operators.
