eaton posi/ baer claw problems

[DirtKing]

I started installing my rear brakes and axles into my new eaton posi and the driver side axle would not slip into the posi after I put the c clip in it! The passenger axle worked perfect. Anyone ever experience this?? Only options I see are removing the eaton, sending it back...waiting for the exchange. That totally SUCKS! Or, grind on one of the clips and see if I can get it to fit. By the way, I'm happy with my brakes, but it took Baer 4 weeks to send them after they told me a week and a half. They also didn't send instructions...(not that I need them, but they're nice for reference.) Also, they still haven't issued a credit they owe me for. That was a month and a half ago. They also forgot to send my brake fluid. FYI
