Or you may find the identical device available in your choice of package so just order the TO-220 case instead of the DPAK case. It appears to me the board was designed to accept either. There appear to be 3 holes for soldering the 3 legs, and a larger mounting hole for the tab - like a #4 screw. Depends on how mangled the area is. Heatsink compound/grease might be in the cards. You need good heat transfer from the package to the "silver" area to keep the device operating cool.
