Hey there,

Thanks for posting! Your window operator can be replaced with the 39-221B Encore Dyad Operator. You'll need either the 39-375 or the 39-451 to replace the cover. The bracket can be replaced with the 39-545 Truth Snap-Stud Bracket. The opposite versions of these parts can be found tagged below this thread.

To determine if this is the correct replacement match, carefully review and compare the dimensions.
