For those that live in South Florida a trip to Gunnar Racing in West Palm Beach should be on your list. They don't discourage visitors and their "museum" is jaw-dropping stunning. They are the real deal when it comes to 917's, 910's, 908's, 962's, on and on.
They were building a 917 tube frame when I was there, it was interesting to see the fittings on the frame to send oil to the cooler thru the chassis tubes.
Camera's aren't very welcome, some personal pics were ok, just didn't want them to be posted on the internet.
Wow and Wow.
