need help : exhaust donut gasket orientation

This is the rear tailpipe section to the muffler via clamp. The donut gasket fell off when removing tailpipe and I do not remember which way it goes? Taper toward the front of truck, as pictured?
Google was no help, under the truck now.... dont wanna tighten it up until I know

Thanks

***sorry for sideways pic, the "top" of pic is muffler section, "bottom" is tailpipe section testing there

 

Well I flipped it. Seemed to fit better.

 

Flat side- face muffler…

Question I have is do you know the OEM part number for that metal donut seal from Toyota?

I’ve searched with my vin but, unable to locate it
Would it be possible to grab your vin# that way I could double check Toyota's parts epc…
