Welcome to the Forum JT. Unfortunately, the answer to your question is there are no parts to be found unless a member here has some ejector rods stored away. This part is very easy to reproduce and can be made to match, if you have access to an example to take measurements. Starting with a 1/4" rod, you can reduce the diameter to around .225". The finished piece is then held in place by a small screw. The only shaping to do is the front end of the ejector rod. If you are not into metal working, a machinist could reproduce one very easliy.
