Damaged channel where tilt spiral balance should be screwed.

Question

As you can see, the channel that the tilt spiral balance should be installed is damaged (in original installation 22 years ago - not me). If I insert a balance screw plug, it would pop out the top. Would you suggest an expanding foam filler above to anchor it in place? I could lower the screw hole on each side, but would I need to buy shorter spiral tilt balances? Any thoughts? - thanks for your time!

In this situation, I would cut a small piece of aluminum to cover the hole, then drill a hole in the new aluminum piece approximately where it was originally in the frame. From there you would just need to use a longer screw.
