Your wanting to weld the back of the lower bars to the under axle brackets? If so then with a wishbone 1 of 2 things will happen. Either the suspension will just lock up and do nothing or it will want to wad your wishbone up.
wow ya just confussed me but never mind bout that set up cuz if i do it asnd i have a c notch it will prob;y hit the frame and the bag and braket will hit my tire
