You don't want Speciality Bill to restore a R/T tailpannel. I handed him two very nice tailpannels and actually agreed to $2800 to restore the best one and get $350 for the other one. One year later, I owe him $3550 and my other tailpannel. Exceptional work but his price one year later was take it or leave it.
About 3 years ago there was an Nos one in a decayed box at spring Carlisle for $2,000 maybe it will pop up again guy dealt in old NOS parts but mostly other brands...
