Negative on washers. It's a bolt diameter thing, not spacing so much. Ex has smaller bolt and will wobble around in frame and booger up the hole and then you'll be welding stuff up to do it correctly.. IF you are creative you might find something at the hardware to make your own, even if it were nylon and only temp until you get the correct bushings. One member on here has alum ones for $15 and KOR sells steel(?) ones for 20 (IIRC).
