70 challenger convt. spare tire bracket

[1966 dart wagon]

My dad just finished up his truck floor on his 70 dodge challenger convertable, and he now needs to install a spare tire bracket, his has some pitting and he was wondering if i could find him one online. I tried looking at paddock and year one with no outcome, so if some of you guys could keep your eye out for a good one i would really appreciate it.

thanks
