Here is a combination grill guard and badge bar that was manufactured by Arnolt Corporation. This one looks like it may actually work as a grill guard. The trick here is that it appears to extend significantly forward of the bumper and overriders, and the front bar may be soft enough to give and flex to allow some additional crush space before anything would contact the grill or painted body shell. This could be just the ticket for fair warning to those park-by-ear specialists.

Thanks to David Walter in Bloomington, Indiana, for these pictures. He bought this accessory through eBay. Unfortunately the mounting brackets are missing, so something will need to be fabricated for installation. It would be nice if someone else has one of these, or a picture of one installed, so we could have a better idea of the exact shape of the original mounting brackets.

As shown here it is blocked up to approximately installed position, although it probably should be at least two inches farther forward. According to the instructions, there are two cast pieces that attach behind the over riders that would support the guard in place. It reads a lot like standard instructions for installing any badge bar, where the brackets would fit inside of the overriders just behind fog light brackets (if installed).
