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
It should definitely be addressed. If that's what the inner well looks like, I wonder what the k-member mounts look like.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.
