Well, that's interesting! I think your asking in the right place, but I haven't seen or heard of anything like that. Barracuda's all came with rear bumper guards, so there would be no need for an aftermarket supplier. I'd guess england export car, probably due to different crash standards. Rarity level is probably off the charts! Value is going to be pretty low due to lack of desireability. Not many people looking for these.

Hopefully some of our Moparts friends in England can chime in with some more info?
