Christopher,
No seal "save the OEM quasi seal" will just drop in because the timing
cover has only a few thou clearance to the pully.
The word from several that have tried to seal up the front, is
to find a pully that is not cracked at the keyway, turn the pully down
to the depth of the machined scrolls, find a suitable seal for the
newly turned pully, then fabricate a seal retainer from a steel
tube that has the correct ID for the seals OD.
The retainer is then brazed to the timing cover, and the original
flange is cut out using a rotary file.

Kind of a lousy pic, but I hope this get the point across.
Anyhow, I wont be trying this one for at least a few months,cause
my new motor is going back together, and there is'nt enough time
to go about doing it this way.
I'm going to just try and see how the OEM seal works.
