I just can't shake it

I might, had it not been for OCD, just have tried to ignore this bit, put some rust 'killer' on it, but alas (or is it yeah) i couldn't, didn't, wouldn't, can't.

Had to scratch my head a bit to try and figure out how i was ging to get this back together again, three panels overlap and join but all spread out in different directions.
Didn't really know what to do, so i just cut all the rust out and decided to take it from there.
