The Carmel Bronze Metallic (paint code "K") looks great, don't think I have seen one before ("poly" is a PPG term for metallic, Ford used the term "metallic").
Other "gold"-ish colors for 70 are:
Paint code "D", Pinto Yellow (looks more like a tan or beige tone)
Paint code "G", Chrome Yellow
Paint code "R", Yucatan Gold (actually looks more like a light green)
I recall hearing the name "Tuscan Gold", but it is not listed on the sales brochures or in the Ford paint charts as a Bronco color. I think it is either a Ford car color, or a name PPG or one of the paint companies used on their color card in place of the name Ford used for one of the colors (this happens pretty often).
Here is a thread with info from some research I have been working on related to the various colors, codes, etc.
