well i started to weld up my top notch so i can put the bag under the notch because there is not a lot of room to put the bag on the rear end so i think im come up with a good way to do it i like it keeps my air line out of the way and u dont see it but i started with 4x4 by 1/4in box tubing for my c-notch and added a 1 in with 1/4 in plate on each side and cut a window in the one side so i can get in to get to my fitting but here are some pic hope u guys like it so far
