You can get the correct rivets.  They are aircraft type, and come in the odd ball size you need.  Chat up a a&p guy at the local airport, or order online.

I took mine apart too and it was and has been successful. If one is  
sort of working then I'd be fairly sure of success. I think it's  
mostly the result of corrosion of dissimilar metals. Once that is all  
cleaned up it should be good. The rivets are an odd size and I tapped  
the top piece and put in Allen head screws from the bottom. Fresh coat  
of paint few if anyone will notice.
