Stop in for a cup of coffee

I just depend on friends here in the real world, and you guys.
Talking to my Barracuda expert buddy yesterday about the speedo on my car.
He goes off on a tangent about the difference on how the 67 and 68 speedo is attached behind the dash, and what to look for to determine if its a repop or OEM. I just sit there listening shaking my head. A wealth of information, great friend to have.
Wife who wants to write a book has talked to him about doing a restoration book. They have them for B and E bodies, no A bodies though. She thinks he could do it with her help.
