I friend Dave who has a stainless shop here in town. He likes to make things. He's been reproducing the hoop bumper for a few years now. He wanted to know if I like to try out something new on my cobra. I think it's 1 1/4" staneless tube. I have the front on and we are going to make one for the back tomorrow. What do you think? It just bolts on to the front of the quick jacks. If your interest in one send me a message.
