I hope this doesn't muddy your thread Bill. If you want to keep it just pics of your build let me know and I'll delete these, but I wanted to post them just in case you can use them for reference.
These are the shorter stingers that Fighter Cat sells that I was talking about. They are a tight fit, but the can be fitted, and they work great once you get them on there. The 110mm stingers might do well too, I don't know. They shorter stingers look good on the hull though, and they're a little sturdier than the 110s.
