Im reinstalling the brackets on 2007 PT Cruiser and I cant remember where this L bracket goes since its been 3 days removed, I mounted the large upper bracket with T bolt insert, and the lower swivel bracket, now I still have this L bracket about 2x1 with a nut spot welded onto it and ive screwed the swivel bolt into it but it doesnt look right to me, what is this bracket for im totally lost.
