#1. What am I missing? I obviously don't have the blow-up dealy for changing tires. Does anyone use them? But what about the right side cubby?

Also, the manual says to replace the tire goop every year (think that's right). Where is the best place to get a fresh supply? And does it have a model number?

#2. This is one of the two 'tabs' on the forward trunk wall. I gather it is for a trunk cover. If so, what does the cover attach to in the rear? I don't see any possible attachment point/points. Just had a thought - or does it attach to the trunk lid?

Where can I get one?

#3. This 'tab'/foot is in front of the seat rail. Is it along with the ones in front of each seat rail for a stop? If so, it seems sort of weird. That said, I imagine they unscrew so that if the seat has to come out, it would be a matter of removing them and 'rolling' the seat forward and out. Bet they're heavy.
