Yep, those really are the standard OEM airboxes from my Darmah and they should be a straight fit, at least onto your frame. Because of their positions under the tank & behind the side panel you don't actually see them. I removed them because I wanted space for a rewire and the new ignition system. I fitted K&N cone filters which do provide some protection but I noticed your carbs only came with trumpets & wire mesh. The latter isn't really going to stop gritty air getting into the bores. Btw the engine breather pipe usually connects to the front airbox but I can't see where yours was routed to. Again, I used a K&N filter.
In that general area, yeah, but pointing down on the ground. I’ll try and take a pic. It didn’t shock me, to be honest.
