Quote: Which set of these shims/nuts do you think will get the boot? On one side for the fender aprons, an ounce was shaved with the aluminum versions. On the passenger side, a whopping 2-3/4 ounces were removed being that there were five steel shims to seat and align that fender correctly. Fairly easy to make using flat stock aluminum and cutting/filing a U-shape slot for the fastener.
Better yet, is plastic shims that can be bought at HD as flat stock. Just drill through a stack and use what you need. Half the weight of the aluminum and easier to work with.
It can even be U shaped slotted fast with a drill bit or die grinder.
