[Rhodes22-list] Dropping the Mast

[johnrowland]

1990 Rhodes--never re-furbished.
 I need a little help from my fellow Rhodes owners.
Today, I dropped the mast.  When doing so, the plate the the mast fits in pulled out with the mast.  It appears that the plate hast three screws.
How do i fix this before raising the mast next spring? Do I use larger screws? Do I try bolts? I have not seen this issue before and do not understand why it happened.
Responses are very welcome.
Thank you fellow Rhoadies.
John
