According to Johnny Burge a former owner of an original & builder of what was dubbed "A Clone more correct than of the originals left" by MCG

There's a guy in Florida that owned a couple when new & Johnny got one from him as well as some other Hemi A body stuff to do his clone

Johnny said the guy told him that when the cars got repainted that was the first thing that got pitched & the holes filled.
They dug around & found one in the shop where they done bodywork & found one on top of a door frame or 2X4 in that building
If my mind serves me correctly he got the hood for his clone out of the rafters of the building too

I think in the MCG article Johnny told the guy's name

Johnny rolled his original Hemi Super Stock Dart in a street race
