Updated SPITFIRE HEADER INSTALL 63-66 A-body

I'm the guy with the angelfire site... you know the "old news" site. To be honest, I'd forgotten all about the headers since I sold my vert a few years back. I'll have to see if I can remember the login to the site to update it.

Good to hear that Harold is making the headers again.I'll have to get back in touch with him.
