Snot,
I just wanted to type that! Welcome! Now, your lids were built using the VEC process, not in the usual fashion as most lids. Genmar had bought that outfit back in the late 90s, and, seeing as they no longer kind of exist, you'll be hard-pressed to find a replacement.
However, my friend Rob Wilhoit, owner of The Boathaus in Sarasota, bought a lot of old small parts molds from WC/AS before they high-tailed it out of Sarasota. Give him a call, he may be able to help. Here's a link to his site...
