[Rhodes22-list] Pop top mast fitting

[recorderguy2001 at yahoo.com]

Hi All,
   I just put my new-to-me Rhodes in the water and I'm having an issue with the pop top.  The block with the anchor point on the mast is not locking in place so the front of the pop top drops.  There's a small pin with a split ring on it that looks bent which I'm guessing is the locking pin.  I'm presuming this is a spring loaded pin that engages a hole in the mast to lock the bracket in place.  Is that correct?  Is there anyway to remove the whole assembly without dropping the mast?  Any advice about how to proceed?

Thanks,  
   Peter
