Crankshaft spacer for automatic transmission

[IHMagellan <IHMagellan@domain.elided>]

How do you go about removing the spacer from the crank in order to convert
from an automatic to a manual?  There doesn't appear to be enough room to get
a gear puller to grab the back side.  As near as I can tell, there aren't any
threads in any of the holes to allow the use of a steering wheel puller,
either.

Thanks for any help.
