This thread is very old but I used to own a BP Tahoe with this style skid plate.
Here are some pics I have. Might have more. It went from the backside of the bumper support to the frame underneath and had aluminum plate screwed to that.
It also had a strap to keep the hood open a few inches with crazy stiff hood struts, had a 2” lift block up front and 2” lift springs out back from a company called Baja designs (I think, I have the springs still I can look if someone cares). They were in Cali and did up fitting for BP
