Well, these thing happen, so lets make it look professional. If it were me, I would cut the bent flange off the proper side, right at the edge of the bend radius. Then take a similar stock thickness and make some angles with, a nice bend radius, and simply extend the part using dimpled rivets along the length to ensure good strength. Use close spacing like the sides.
If you can not bend your own (and you should as you will need that skill and tool eventually) then maybe the L shaped bracket that is the second support for the control cables might be a good, cost effective piece. You can find the number from the drawings.
Once one gets off the beaten path, it is a little more work to get back, this I know from repeated experiences. (like yesterday - remaking the fuel pump to firewall tube, when the Vans tubing order arrives that is. . . . )
