I want to attach the brackets for a towbar on my 97 Wrangler.

I was planning on bolting a heavy piece of angle iron under the front bumper for the towbar mountings brackets. As I look under the front bumper, I see the 2 torks bolt that could be used and was thinking of adding a bracket to each side, one to a bolt on the steeering gear box and the other to one of the open holes.

Is this enough to hold a tow bar? I doubt I would use it much.

Thanks for any ideas.
Doug
