It turns out I don't need a new ejector. I discovered that the ejector was not slipping behind the rim. I was able to push it with a pick and it snapped behind the rim and then ejected fine. So, now I just need to figure that problem out!
CARTRIDGE EXTRACTION AND EJECTION
When the lever is lowered the fired cartridge case is automatically extracted and
ejected. Check the chamber to be sure it is empty before closing the lever. If
automatic ejection is not desired, remove the forearm and back-off the ejector
strut adjustment screw until the ejector spring unit can be removed.
(See Figure 6.) The ejector will then function as an extractor only, and the
cartridge (or fired cartridge case) will be partially removed from the chamber by
the final downward motion of the lever. If the ejector spring unit is replaced, do
not over-tighten the ejector strut adjustment screw because that will bind the
action. The force of ejection can be altered to some extent by moving the
adjustment screw.
