fold, trim, grind, trim, grind

I looked around on the internet at how other people make tunnels and concluded 2 things

1) This is an unbelievably common thing to have to do.

2) They all look terrible.

This sort of freed me of worrying about how bad this will look when I am done.  My neighbor had a metal brake that will do 16 ga so I stopped over with my tunnel this evening and we folded it up.  I put it in the car and it was pretty close.

I spent about 2 hours trimming and grinding to improve fit at the firewall. I will do more grinding cutting and folding, and will likely have to patch in some spots.
