One thing that is often overlooked are the bolts used on the fenders for attaching to the fender frames and attaching light brackets. Modern bolts of the correct size have one size smaller hex heads than the original and are shorter in height. However the nuts available now are the same size as the original across the hex and thicker than the original heads. I bought a hundred plain steel 3/8 nuts from McMaster and made a jig to turn them down to the correct thickness then cut threaded rod to length and inserted it into the shortened nut with a jam nut to provide 1/8" space from the top of the rod to the upper nut surface, filled it with weld and turned it smooth on the lathe.
It does make a difference in detail even though seemingly small. You will need to do 12 in all for your 8N. If welding is too much you can use Loctite maximum strength thread lock (be sure to use the solvent that goes with it) to attach the nut to the threaded rod and fill it with JB Weld and then file to finish. That works also and these fasteners do not see much stress and tightening them in place is done with the nuts under the fender so only need to restrain them on the painted surface.
