you cant put a coil on your shock you have now, you need to order a whole new shock. that being said, take the shock off the bike, and measure from the center of one mounting hole to the center of the other. that is the eye to eye length. then, measure the length of the shaft of the shock, that is the stroke length. you may need to round to the nearest size due to your measuring, but you'll be close enough that its not hard to figure out which one you need.
