Heel Guards for AC nerfs?

[fastrnrik]

While practicing today my buddy landed wrong on his LTR and ran his leg over. I'm pretty sure he broke his ankle. We had JUST been talking about neither one of having heel guards too.
Anyway, I have never run heel guards. Ever. But now I think I may want to add a set to the R.
What kind of heel guards are out there for AC nerfs? I have the pro peg nerfs. I noticed there's holes on the back of the footpeg, so I'm assuming they're there to mount heel guards too.
What are the options?

I would also like to know what works so I can put some on mine.

i dont think you can add heel guards to pro pegs.. but i think some pro pegs come with heel guards...
