I was speaking with Jim as I submitted the previous post (couldn't find a pen), and Yes, he is still the N. American ACOC registrar. He does not, however, have a computer - so he relies on phone and FAX.
As he does not use a computer, he's not seen this forum.
He is restoring his Fastback, and I've filled him in on some of what others have been doing in regard to the heat issue.
He's installing insulation, and would like input on what material to use. I can't recall what the (German?) material is called that is used on present-day race cars and aircraft. Anyone have a suggestion?
