Wow.....that's not good. Why was it cut? Anything can be fixed, and more detailed pictures would help us assess better.
Also yes I've noticed the shotty wiring job, I bought the car last year and just drove it and stored it. Planned on fixing things this year.More pictures for reference
I think the best thing you can do is pull the nose. It's really not that hard to do. Get a good look at BOTH sides of the inner fender frame area.
Looks to me it can all be welded. If you do not weld it, it will only get worse.
