I just converted 2 of my 8-shooters to four 4-shooters. So I have the frames and aluminum crossbars available for sale. Evidently, if you're to buy just the frame and crossbars for a 4-shooter, from Bumper Boy, it will cost $175/frame. I can only imagine what an 8-shooter frame would cost. Therefore, I'm looking to get $75/frame plus shipping. The pic below doesn't show the crossbars, but I do have them and they are included.
