I need some advice.. I took my 68 to a point judged show and was knocked badly on a item I was told was correct.I have a disc brake car and was told a disc brake car from the factory received a different trim ring then a drum brake car. drum received a part # 9781480 vs. a disc part # 475019.As near as my knowledge this is true but was told by a judge all recieved brushed cause his drum brake car had it.So I am going to a all pontiac show this weekend to get judged should I put the brushed rings on (which to my knowledge is wrong)or keep the polished ones on? The other thing is even though I have the part numbers I cannot approch the judges untill after the show
