Aaw, that's not so nice!
Why didn't you build this thing the logical way? The cage now makes the inside almost inaccessible for someone who wants to weld something, the pipe insulation around it could catch fire while welding the holes.
Why did you use the standard dials and surrounding if you have to smear 20 kilos of putty around it to make it look at least half decent? A simple aluminium sheet folded a few times would have been cheaper, easier to fix and looked better.
I would have cleaned, welded and fixed all the stuff, painted (inside and out), then I'd have placed all the stuff in the car.
But hey, just being constructive in criticism, the car has to fit you, not me!
