It's tough to be sure but I suspect that the part shown in your photo may be part of the 39-536 pivot slide, which works with 39-239B operators. Take a look and compare the specifications below to an undamaged part. Thanks for posting!

Hi Casey,
I think you nailed it- that looks to be the part! Will order a few and get them installed.
