The judging sheet should be available on line at the MB Club web site. It has been updated and I do not know if the current one has been posted yet.
From what Pete told us (I judged chrome lights and trim for the show cars at Starfest), the battery needs to be original, Varta, tar top, but no point difference between the two. There are no extra points for the rub strip tire, but all five tires in show class need to be the same. In street, the spare can be different.
With the MB club, the street cars get extra points for age, up to 30 years, and extra points for mileage, up to 300 K miles, I think. So a street car, can get a max of 430 points, 400 for the four general areas, 15 for age, and 15 for mileage. The show cars get no concession for age or mileage, but the fifth category, as Joe points out (chassis undercarriage) is worth 70 points for a max of 470 in show.
In the MB club there are no extra points for the fun extra stuff, luggage, trouble light, etc.
I did pay attention to the official MB logo on the soft top glass, not many cars had this.
The judging sheet is also very specific for the alloy wheels. As best as can be stated, a car after June 1969 with alloys is alright and not points off.
