I think I'll leave the tab on, unless I feel reel good and can get at it with a good needle nose but, why, If I get the coil in and the bolt fits flat. I don't intend to use this port. I almost thought to just fill it in with some epoxy. but that can be a last resort --- a lot of thank you's out to you all for the help. all these blunders become good learning skills.

Capt Terry,

You realize you will need a "helicoil tap" and the corresponding tap drill. They are not the same a standard tap....

You should be able to find a helicoil KIT on eBay or amazon that will include the proper tap, drill bit, insert tool and a few coils.
