I'm new here - looking for a nice Scamp
. While reading posts I see people looking for hubcaps. I don't know if this will help, but if you have 12" wheels with 4 clips riveted to the wheel to hold a hubcap...I have those hubcaps.
They're new old stock and as far as I know the only supply left in existence. You can see them and the wheel they fit here
Hope this solves somebody's dilemma!
