After coming home from work and viewing my problem with the T-nut in the wing from a different perspective, I decided to drill a hole in the root rib to access the area that I needed. I also decided to drill both wings while I was at it. Here are a couple pictures of the holes I drilled carefully using a 7/8” spade bit. FYI there is a couple of pictures of what the T-nuts in these wings look like. They are plastic by the way. Also you can see how I used a tie wrap to feed the T-Nut back in place. I used a small amount of “gorilla” glue spread with a tooth pick on to the T-Nut.

I also threw in a picture of the ugliness of using silicon to seal the hole for the fuel lines.

Here are the final fit pictures of the exhaust header and muffler.

And lastly the shots of the fuse wrapped with some saran wrap waiting on the wing with silicon to be put in place to dry overnight.
