Corey and I damped output arm MC baffles. The figure shows the locations of all dampers. We mainly followed details in: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=38757  but placed an extra (fourth) cork at the top of each baffle, and damped one panel gap on the outside, where most of the gaps are not as wide because the bolt spacing is closer.
