I did the same as audiofetish. They work real nice....as stated, cutting out the holes was a bit time consuming but a good dremel tool helps out with this.

I'd have to do a search but they also make a real nice system (had it on my Ford) that mounts on your reciever hitch...you may not have that on the limo though. I could find it for you if you need.
