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.
