Can anyone point me to some good on-line info on plugging old through
hull holes in a fiberglass hull?

Unless you have really good reasons not to, I would fill the hole with
a through hull fitting. It would take a really good repair to refill
the hole with anything that will be stronger. Why not just rebed the
fitting and blind it off?
