MOTractor -
On each side, right at the level of the "tongue" - a pin on each side, so I can fold the guard forward. I took the basic guard to a welding shop and they did the expanded metal and the tongue. It wasn't cheap but then again neither is repair to a radiator/ new battery/etc. Its saved the radiator 2X that I know of and I'm careful to the extreme.
Thank you. My LS has a nice heavy guard, but it is completely open in the front. May have to steal the expanded metal idea.
