Crank Operator 39-172

A home owner from Minnesota says:
I am trying to find a replacement operator. 39-172 is the closest I can find, but the top arm of mine measures 4 1/2 inches. Do you have one like that?

Tom from SWISCO responded:
Ah, no. Unfortunately not. You'll need to drill out the fasteners to remove the link arms from both the old and the new operator, and then install the old link arm onto the new operator using a 62-014 rivet. It's a little involved, but you should be able to make it work. How's that sound?
