Update:
The space inside the frame was plenty large enough for the dremel wheel to cut the inside of the pin off flush with the frame. Pin pulled out easily. The strip of upside down tape that I placed in the bottom of the frame picked up most of the aluminum dust, and my Shopvac picked up the rest. (Had to be careful with the Shopvac though, because the suction is strong enough to rip off wire connections and small floating parts.)
My replacement parts will be delivered this week.
Thanks again for all advice.
