Hell double points and all. I think that the double points should be for speeding not minor offences. I would really appeal that one.
I think
www.finishline.com on the forum here has a number plate bracket that bolts onto the lower bolt on the front jack..

Maybe someone else but I have seen it.
My plates swings up also...
I had a similiar plate set up on the '37 roadster and the plate was up. I was stopped and was about to be given a ticket when the other cop came over and talked about the car. It gave me a little time to think and I told him that obviously someone careless had backed into the '37 and pushed the plate up with their tow bar.
He told the other guy to forget it and leave it.
However, he just stated that I should check my car before driving and ticketed me anyway. Hell I just took the cost off their Christmas fund raiser..
