I also have a 405 but haven't had the need to replace this. However heres a link to our carver forum that although isn't the same boat may provide some insight. You might also try the search feature on here for possibly more. I bet that Taylor made this also. ......there were several year models leading to the 405 that had the same windows

You might could try and match up the profile of the weather stripping with a local glass or online dealer.
Greatlakesskipper might could help also. Please post if you do find the correct rubber for future references
