Well I had so much trouble getting my old one out, I had to drill it. I also had the same problem finding an appropriate replacement pin in my area. At that point, I shifted to a allen head shoulder bolt with nylock nut in place of the taper pin. It was a simple matter to drill out a straight hole using the remains of hte old pin to align the collar on the shaft. It is not that critical of an application to hold the end collar on, so I had no issues doing this. It is also a lot easier to get off if future teardown is necessary...
