Hi,A few days ago I went to install my spare tire on my 86 300SL and found that my lug bolts were too long. The spare is a black I think steel wheel that I think is original. The one's on the car are the alloy 15 hole ones. It's the European model with the smaller bumpers. I just wondered if I had the correct wheels on the car or should I get the ones to match the spare maybe with hub caps. I kinda like the looks of the older wheels anyway. Any advice will be appreciated. Thanks!
