The inner fender grommets in my '71 280SL are missing and I'd like to replace them. The paint on the car is light beige with tobacco brown interior/wheel covers/hard and soft tops. I only found a set for sale from Vintage Euro Parts, but in the picture they're blue (I figured they'd be black). Before I consider purchasing, what is the proper color for these grommets in this car built in October 1970 /
