Fog/Spot lamp covers

[Coopman]

Hi, i'm new on here. Before i get into anything ive been driving a R56 for the last few years and just purchased an R53 to add to my collection of 2 haha. I was just wondering does anyone on here know much about where to source cheap covers for fog lamps. I have four lamps across the front of this R53 i want to cover as they seem to be prone to rusting and all i can find is plain black material ones on eBay for about €75 including postage which is a little bit too expensive in my opinion. I'd like to get lucas ones on there but they are only made for 6" inch + lamps and i have 5" inch on my R53. Any suggestions as to where i might pick up a set? I want to get the material ones as im not a fan of the plastic covers.I dont mind if they are plain or have logoing on them as long as they are black.
