Finally approaching the end of my restoration project on an old Trac 14 and can't wait to get it in the water! But a question (without all the details as to why): Can you glue in drain plugs w/ 4200 or 5200 alone without using screws, or are the screws absolutely required? (No plug fits the original holes.)

I know that I can fill and redrill new holes, but I was wondering if that's really necessary vs. just putting it on w/ (probably) 4200...

Thanks!
