Looking to replace

Hi there!

Thank you for reaching out to us. Our 39-035 and 39-036 come to mind. The link arm for this is 3-15/16", when measured as shown below. If the length doesn't match up, you have a few options. The first is to install the operator to see if it works as is. You could also try repositioning the stud bracket to make up the difference. If those options don't work, you could drill out the old and new link arms and then install the old arm to the new operator. You can use the 62-014B rivet, which will have to be hammered in. I recommend doing it over a metal plate if you have one.
