Thanks, Steve. I appreciate the compliment (and those of others as well). I have been very fortunate to have had help on this forum from a number of sources but Ron Lathrop of course has been a HUGE help in taking what is done here to "another level". I can't say beyond what I hoped because I hoped BIG when I got this started.

Ron just helped get us there much quicker than I figured and for that, I am extremely grateful. (Thank you, Ron!!!)
As for the Yenko car, yes it is the one that Smokey built in '67 and it is the same car driven by Don when he won the Citrus 250 Nascar GT race in '69 (where Parnelli Jones debuted the Bud Moore Boss 302).
I don't really understand why Bud Moore switched the usage of his various style of mags around. Maybe someone else has an idea? I think there was concern about the American mags being more prone to breakage than the Minilites but if so, why use them at all if your worried?
I have seen the Firebirds with spoilers at some of the other T/A events. I'm not sure why they aren't on there for the Mid-Ohio event. Yes, Mid-Ohio was a relatively narrow and definitely challenging course. It sure looks like a fun place from the viewpoint of being a spectator and I think the drivers like the course also.
