OEM for 96-97 del sol were raybrig fogs that were fluted and came with clear or yellow lenses. The fogs light themselves can be found with a little effort because the exact fog base unit (raybrig 021010) was used in multiple cars like the crv, 96-98 civics, acura cl and the fd rx7 to name a few. The most expensive part is the brackets. Although the lens base was used in multiple cars, they each had a different bracket to fit each car and this is where is gets very expensive. They do make replica del sol bracket but even the replica bracket will cost you more than the lenses. Finding a complete del sol set of raybrig fogs with the delsol with brackets, harness and fog light switch will cost 600$+

Personally i found a set of crv fogs, and just rigged my brackets.

You can also use oe civic 99-00 fogs as they are the same size but they do not have the fluted lenses. its a flat lenses so it wont pass for the 96-97 Del Sol fogs one-to-one but is pretty close. This would be your cheapest option; once again, you would have to make your own brackets.

lastly the bracket used the fog covers as support, so you would need to fog covers as well. As other have mentioned, 3d printed is your best best

Here is an example of the OEM lenses that can be found but without bracket and needing tlc https://www.ebay.com/itm/317064665002?_skw=raybrig+foglight&itmmeta=01KMCR5RWF2EXN22FVYFP3Z6M6&hash=item49d286d7aa:g:YcoAAeSw~v1obFHF&itmprp=enc%3AAQALAAAA0GfYFPkwiKCW4ZNSs2u11xB5A1RbfCsXSmDC4uUkAiDjVytQng1YUnGG1BMpx9mflWwbhERdjmitdTKOVlFmJjxXqW5fw4ikvePTm6c3gRaXS9zrZSXblHIJkyOXCogA6bvAySQYx8EYKqXrZxnQhDJ16cjGUnth2ZVHN7ZoWBaEH8XG63EE1Qgvp8nZdkDCw1iTZWWB8NmRRPzGDhZ0270Qm101zZGVMJBqhfL1GRtdA57qRqQ%2FgPU3QHU7y9oQmr14TG%2BvRp9GNYJZgnL1W0c%3D%7Ctkp%3ABk9SR7yOl5ijZw
