I'm finally getting around to installing a new spring plate and bottom plate on a 1969-70 sunfish that I bought this summer. I have all the parts, but the wood backing blocks are stripped to where I can't tighten a screw into them. I just opened a hole in the deck for an inspection port and it seems to me that the blocks are still in good shape. They aren't rotting out and I'd rather not rip them out and replace them if I don't have to. I'm curious what everyone's thoughts are on what I should do, or if anyone else has dealt with this before. The one thing I thought was that I could fill the screw holes with either polyester resin(which I have a lot of now from another repair) or wood epoxy and then redrill the holes. Does that make sense, or is there something else I should do? Thanks!
