Is it possible to find siderails that fit within the length of our fender struts (10 1/4 inches,or go shorter?--sorry not metric) and match up one hole and drill the other where we need it ~5 1/8 inches apart...and then be able to find a sissybar to fit the width of our fenders with these siderails? Isn't it all or nothing with the Triumph sissybars and luggage racks--you can't remove the luggage rack or interchange tall and short sissybars? I have almost given up.
