Replacement Lens for WC Nav Light

[unbusted67]

I have wilcox critendon nav lights and I need to replace my port lens but I can't find a replacement anywhere, I tried to order from these guys

Seas The Bay - Hardware

but the order never went through and no one responds when you try to contact them. The lens I am looking for is about half way down the page, they are calling it the red glass marker and the model I am ordering for is the NOS side marker lights seen at the bottom of the page. If anyone has any leads I would greatly appreciate it.
