? re. reinstalling deck hardware

[2Sheets2Wind]

At the end of last sailing season we purchased a vintage 1965 fiberglass sailboat 19' (Paceship Moutte) in length. The deck paint was solid but badly faded. So I've gone out and purchased enough primer and Interlux Brightside (one part polyurethane) to give the boat 2 coats of each. I'm in the process now of stripping the old paint off the deck. The perfectionist in me wants to remove all the deck hardware and do a great job. I am concerned about reinstalling the deck hardware.

My main concern is that some of it may be actually bolted to the deck -and- that without separating the deck from the hull I won't be able to re-bolt the hardware back on due to lack of access.

I know for sure that the rear port cleat is bolted on because I can see it, but can't reach it. Is there some type of general fix or work around for this? Or should I just let these sleeping dog lie?

You assistance is appreciated.

Have a Great Day,
Jim
