ok so I'm gonna take every ones advice and go with fixing the notch.... because I guess I would be an idiot if i didn't listen to everyone lol
what I think I'm going to do is cut the middle of the notch (
red line), and have a piece of tube steel bent up to fit tightly inside of the "old" notch so that i can stretch it the distance I need to to make everything work(
blue square). then weld the two pieces of the "old" notch to the smaller tube inside, then make up some small pieces to fit in the "gap" between the two "old" notch pieces and weld those in for a cosmetic look (
purple square) and then grind everything down so you cant tell I ever had to cut it..... =) between the smaller tube the individual pieces and the bag bracket all getting welding in there i think that it should still be structurally strong enough to support the air setup and abuse it will take.
