Does anyone have a source for this type of tow hook?
Or, show me the setup on your NA track car.

 

I used a tow strap on my old NA track car. I had to slightly enlarge one of the holes in the bumper that was above the fog light, but managed to use a low profile bolt to secure it. The nice thing about the strap (aside from not being a shin hazzard) is that it can be pushed in behind the bumper out of the way when you don't want it out. Sorry for the crap photo, hopefully you get the idea.
