Mast upgrading on Waxwing

Since I have the mast unstepped, I’m going to upgrade all the lightning, wire, vhf, etc. I sure there will be some hardware that needs replaced as well. If anyone here has done this and has some tips, it would be much appreciated.

Has anyone replaced the masthead sheaves? If so what size and brand?

Mast head removal?

Installed spreader lights?

Boom neck parts?

Spreader arm issues?

Rigging issues to be aware of hooking everything back up?

Thanks! Tom
