Valuation Needed

Yeah, I was one of those high schools kids (Dons) in my loud and fun '65 Mustang that my dad helped me build. But back then it was soooo different (almost rural) than it is today (more like the Midwest where I live now). Hard to imagine someone would target such a specific part for your '65.
The Acalanes Dons. I was a Del Valle Trojan class of 76. It was much less built up when I arrived in 1970. Lots of girls I knew had horses. It's much more hemmed in now.
Pretty sure the quarter panel was stolen by a metal thief. My BBQ grill, Arien roto tiller and a nice road bike all went missing one day.
