Thanks, everyone. It sounds like I just need to punch out the rivet casings (not castings) now. I have the cleat and old rivet out and was having trouble getting out the casing. The rivet hole on the mast is still snug.



How should the new casing fit in the hole? Should I be able to push it in by hand or would I need to tap it in with a mallet?



As you can tell I'm not very handy.
