I know there is already a thread on doing a rr swing arm on a F4, but instead of using the stock rr swing arm I want to cut where the axle goes onto the swinger out and weld the back half of the F4 swinger on it extending it about 7 inches or so but I need to see if any one will measure the chunk of aluminum where the axle and chain tensioner is welded to the wing arm just to see if the F4 swinger will fit.... Ill show you a pic so you will have a better idea of what Im talking about... the red lines will be what I need measured. I know this is a newer rr swinger but I need the measurments off of a 03/04 swinger much help appreciated thanks....
