yeah thatŽs easy but if you multiplie the inches per 2,54 youŽll get a unlevel sign. So i canŽt find this in a DIY-store.
For example xou have a 10-24 inch washer, youŽll get 25,4-60,96 mm but in the store you must fount 5mm-24 washers according to metric size from Matthew Miele. So if anyone have the metric for the front mount vest please uploade. Thanks
