Yes, I searched for 30 minutes on the DIY and Tech areas, plus google. No one has said! I know it's a canister, but how many bolts, next to what, approached from above or below, I really feel stupid on this.

Also, there is just one bolt for the drain plug? Located at the driver's side of the pan, front bottom edge?

Yes, I took the belly pans off. The car is even up on a lift, patiently awaiting my return tomorrow, armed with knowledge and a socket!!
