The deck rework is not a big deal… but might give sensitive people difficulties to sleep at night. 
I saw it as less work for me repairing the deck than buying a new one and have the whole routing makeover done again. I wouldn’t have done the deck repair if the deck was in any way moving or flexing a lot. It was very stiff.
After the hit I rode the deck home standing majestically on the front truck like a hood ornament (to avoid any more damage)
The deck was forced and (twisted?) into the hardest turn it could possible imagine… causing the enclosure to press against the ground.
Easy fix. Some epoxi and sanding… adding more of that dirty feel to the enclosure which I seem to like
Here is the largest crack. And some pieces broke lose from the base plate seat
Here is another crack in the same direction
My bracket got a bit bent and the bolts slightly crooked. This one I hammered out and replaced the bolts.
I drilled deep (5cm) small holes in the direction of each crack. Then twisted the board (the wrong way) using clamps to get the cracks to widen slightly. Then injected the kind of glue which expands a lot, using a syringe. Forcing in as much glue as possible.
Then tightening down with clamps. The baseplate seat cracks I rework with epoxi.
My printed charge port holder broke and the wire isolation got torn
I modelled a new improved version.
Now sitting flush
So far the board has run 640km. Last 400km has been after these fixes. It seems to be holding great and I have not seen anything alarming regarding the deck so far. I hope it stays that way 
Here is a picture from the other day. Sharing a pineapple pizza in the sun in the company of the Rat board
Sometimes life smiles at you, better enjoy it.
