Sweet, that part number has been discontinued, but my local dealership was able to round up a couple pairs and has them waiting for me. My wife has the car in town today getting new tires mounted up on it, so if she can make it over to get the mudflaps picked up before they close tonight, I might get them on after work.
Well, got them on and they look great, thanks everyone.
CADAVERFE, on our car anyway, there was only one plastic clip on each rear wheelwell that I was able to use (none on the front). Mounting consisted of drilling four holes in each fender well and spash guard (5 on the rears to accomodate the plastic clips) and mounting them with the body screws that came with the guards.
