That for sure is a very special combo. Is there any way to get ahold past owners for the fender tag? Hey if there is a Big Block K member and a VIN tag that matches is pretty much worth restoring for me IMO.
Take a look at the radiator core and trunk gutter numbers, maybe the build sheet someone else has found it and posted up around here.
the previous owner bought it from an estate sale. That owner had passed away and son was selling the car. I could try and contact them to see if any other details can be learned.
