I'm trying to match an awning operator. Your 39-084 is almost an exact match. If the old arm extension is 2-1/8" verses the 2-1/4" on the crown, would it work properly installed?

I think it'll work, yes. You have some play when it comes to these link arms, so a minor difference in length won't be that big of a deal.
