I found some that work quite well by searching "wayfarer fade" on ebay. It took a little playing around looking at glasses to find them. The only difference is that they don't have the silver studs in the corners, but I'm adding them with beads tonight. The costume should be passable by the con I'm doing three weeks from now.
Thanks for the links! That helps with figuring out how to do his cardigan.
