Subject: Rear fender mounting question

Hi all,

I am putting the rear fender on the Eldo, and I wonder if there is
supposed to be a pair of washers or other spacer part between the fender
and rear frame tab? It looks like the fender contacts the frame tube
before the tab, leaving a gap at the mounting holes, so to tighten down
the screws looks like it will dent the fender.

TIA
