The seal there referring to is the pump shaft to converter, it's just a single wrap Teflon seal.
when i was doing mine, Russ told me to forget the wear ring, and wither place the seal in further or not as much so that the seal rests on another part of the crank.
i put the seal on so i just see the groove on the outside of the seal,
i havnt driven this engine yet, but i have about an hour and a half of run time on my test stand, ZERO leaks.
I pulled the trans out to change the rear main seal on the engine. Pretty sure there is no other way to do the rear main seal on the engine... the seal DSL Dog was talking about was the TC pump seal on the tranny which he was saying to change out due to the wobbling flex plate.

You can change the pump seal if you want. But with the converter attached to the flexplate, it will not wobble.
