For insurance just put kph sticker over the mph. That would be compliant in my books considering it's reading right.

I doubt they will even notice, they have that much other stuff to check.

If it's still the same it was a few years ago for our Cobra, it's basically one big roadworthy check:
Check all lights, wipers, horn, seatbelts, squirters(make sure it's full of water) etc.
Check steering, wheels bearings, joints etc for play.
Check brakes on rolling road test unit.
Drive over pit for under inspection, check for everything including using correct tensile bolts, nylocks etc where required.

You should be right. It's a lot harder to get half finished gel coat Cobra's through...they get a lot more picky if it doesn't look well finished off.

You will stand around most of the time talking to the cool pit guys about how great your Cobra looks. Just be nice and approachable.

I would also recommend not knowing too much, practice these answers if required "That's what the engineer said to do", "the manufacturer made/assembled/installed that bit".

Good luck.
