On an information search to identify the lewmar hatch style and sizings on my 87 ODay 40. I believe they may be the rollstop model.

My plan is to remove, remove any wet deck core, cut new acrylic, replace the seals, and rebed.

Any info on sourcing materials or tips on the process would be great.

Try looking here. I replaced mine on my '87 O'Day 322 with medium profiles I got on sale from Defender. Pretty much just swapped them out, after cleaning up a bit with some epoxy. If you're using the same ones, just go for it. It's a straight forward job. If you have any core rot just scrape it out and fill with epoxy.

You should be able to find cast acrylic at a local plastics shop. I found that to be a lot cheaper than Hatch Masters. I've done a couple of my smaller hatches but the large 2 had to be replaced because the frames had cracked under the hinge where they were welded. Take a good look at that area because it is a common problem with them. Mine were "SuperHatches" so if yours are the "Rollstop" you probably don't have that problem.
I bed with butyl tape from "Marine How To".
I replaced the 2 large ones with a pair of Ocean 60's. Pretty much a drop in but the mounting holes are different so you have to redrill them and take care of the old ones.
