Glad to see this thread! Keep the posts coming. This plane has been on my short list for years. I believe Robinaire did the nose strut for the one that flew at Top Gun a few years ago. It was build from this plan. Lee is a member of this site so hopefully he will join in.
Here is your source for exhaust stacks. Good stuff! I have the stacks (and all the other bits) for my P-40B and the quality is first rate. Can't argue with the prices, either.
