I bought the flexible chin spoiler from this Ebay seller: comtechknowledgies
It was round $35 and I think the quality is very good. Installation wasn't too hard but I needed a second set of hands. Getting the curves right was a little tricky.
Pulling the steering wheel wasn't much trouble at all.
If memory serves:
Disconnect battery
pop the top and bottom covers off
Remove a couple of screws from behind which attach to the air bag
Pull the air bag (unplug the wires)
Make a scribe mark so the steering wheel in correct placement
Remove bolt or nut
I wiggled the steering wheel from side to side and it came off. (I bought a puller but I didn't end up even using it.)
I uploaded some videos that I recorded on my phone:
