I sort of told Dan Warner I'd drop this issue but I did find it curious that the LN7 ran H and G/GT here, but GC, Alt and CC later. Rules have been rewritten to clarify the issue.
We spent a lot of time with Don Debring at Bonneville over a couple of years and I visited him at his house in CA later. Really nice guy, now passed. He kindly gave me a set of his plans that I modified for my size, engine/tans and capability to build my liner.
