Oooooh WEEE! They are SOME KINDA FANCY!

As you can see, the deluxe one is on the right. Behind it is just the cap. It really works nice and is worth the extra loot, I think. They sell for $75 each and is money well spent.
They open without tools, which is a big improvement on the standard caps. The standard ones require a screwdriver or something to lift the little handle out of the well. These are machined out of a slice of aluminum billet and are top notch!
TIP: get them with your wing kit so you don't have to send the standard ones back later for credit!
This is what they look like cleco'ed into place:

Pretty slick, huh?

The tops are machined so that the curvature of the tank skin is taken into consideration, too!
Really nice!
