Re-using transom holes

[marc00]

A couple questions:

1) If I'm reading you right it sounds like I should redrill the holes a little deeper and thicker than what's there now so I can hit clean wood and create some solid epoxy for the new pilot holes. Considering I have 4mm holes now would you go with 5 or 6mm holes?

2) Where is a good place to order glass supplies?

Thanks for your help. This is my first time at this and my transom is original so i want to make sure it's done right.
