The height of the sleeve bag when completely compressed is approximately 4 1/2 inches, so the height from the underside of the bridge to the top of the over-axle mount should be the same. | 
With the over-axle mount positioned and the bridge placed directly over the axle, the distance was measured to determine the height of the legs for the bridge. |
A cardboard template for drilling the bag mounting holes in the bridge was made and then traced onto the underside of the bridge at the outward-most positions possible (determined earlier when Michael test fit the bags on the bridge and axle). |
