You could buy some fog light blanks $22 each from bmw.. then cut out some circles and mount eurolites in them.
are you existing ones cracked and pitted. i have a brand new set i would sell. i'm not happy with the way they fit on my M-tech kit so i'm gonna look at my options.
I have a few e30 parts for sale, updated often, discounts for local pickup/delivery. Check out my eBay
account for details.
