Webbing strap fixed, as already mentioned, to the bottom of the front box, I don't have the original chassis but you can fix through the original but worth putting some additional reinforcement inside to spread the load (again, as already mentioned!).
The webbing strap can be folded neatly to reduce its length and cable tied under the nose via some neatly drilled holes. - can do this inside the nose depending on where the strap is attached to the chassis but this would be harder to access with the front grill in place.
Have the above fitted on my car both front and back (rear is wrapped around the rear hoop similar to where Certified recommends to attach the winch cable of a flat bed truck) from when I raced it as you have to have recovery points for obvious reasons.
Would post some pics but I'm away with work and many miles away from my car atm....
