Charles, I changed out my 5.2 to a captive mast base last year. I have the old non-captive with the old rod and bolt somewhere. I will take a look this evening and see if I can find them. I'd be more than happy to send it to you (no charge) if I can find it. You know that the ball is smaller on the non-captive unit although still available but expensive.

Regards,
Mike
