Part number for the Fuel Tank Cap?

I want to buy a couple of extra fuel tank caps for my RV-8. This is the standard cap (not the lockable one) with the flap that looks a little like a butterfly that you push down to lock the cap.


As near as I can tell from the plans the part number is:

T-406A

Is that correct?

Thanks!

Looks correct

Yes.
