i think you could get away with cutting/drilling a hole for the lights to go in, besides, think of how much it would cost to buy the fenders and have them painted! First off, it may be hard to match your paint, especially if it sits out in the sun alot cause it maybe slightly faded and this will standout alot. Also it is ALOT more work, but the side markers do look good. i have a 95 model 325is so i haven't been faced with this problem myself but if i were then i would just drill/cut the holes, much easier.
also you should be able to do this yourself fine, just makesure you measure right and they'll look good.
I wanna see pics when you're done to see how they turn out, but should, look just like stock 93+ models.
