Then again there's always Paul Castle at World of Motorworks?
However, I'd recommend your safest bet would be to wait until Nancy or Russ gets back to you from GN Restorations.
They are located in PA and both frequent Kirbans' Performance open house so you might reach out to Dennis to try and get in touch with them.
I've personally met them there on several occasions & can vouch for their credibility. They are a stand up vendor!
FYI....they are on facebook too
