Hey Mike; Your reference to your 73 RSR Jogged my memory. Your RSR is 0386 ?? I think you were in my shop about 3 years ago. You were referred, I believe, by Thomas Shaughnessy. He was my neighbor. Your number is in my phone. So I think you have heard of me. Don't assume you don't know me. I have had a lot of real period Porsche race cars and parts in my shop over the last 35Years. I just don't tell everybody about them. I have nothing to prove.
