I bought an adjustable tow-bar setup from Harbor Freight that I'm going to adapt. (I know, I know, cheap Chinese crap).
There's not a whole lotta structure to the Rapage bumpers, but if you look carefully, you can find the strong areas.
I think I'm going to be able to bolt the HF mounts through the headlight "recess" area of the front fascia. Directly behind/underneath this area are the 2 main steel bumper brackets which extend back into the frame horns.
It should be solid, and if I can ever find a set of the OEM headlight covers, these mounts would be hidden behind the covers (P4286820 and/or P4286821 for those of you who might have a stash of mid-80's Mopar Performance headlight covers).
I have been looking for a set of these covers for almost 2 years, and have not found a single set. It's not that I'm not willing to pay someone's price, it's that I haven't even seen 1 pair available for sale.
Steve.
