2004 subaru forester cv axle removal

[lesliemw]

Trying to replace my front passenger side CV axle.  The old one broke
while removing, and there is a piece remaining on the end that goes into
the motor - I can't figure how to get it out.  I have the new one, and I
can see it is held in place with a c-clip (I think that's what it's
called....it's a thing c-shaped ring that fits into a groove on the end
of the axle.

 

I've tried using a pry bar on the top to force it out, but no luck.  Any
advice or tricks on how to remove the remaining piece of the old axle?
Pictures show view from the level of the wheel looking in, and then from
top down through the hood.
