Looking for an air filter, 62 Ninety Eight w/ 394. None on eBay, Napa, Carquest, AutoZone, Oreilly, Fusick, all out of stock, no new production planned. Despite what a search shows on eBay, none of them are correct size ( I’ve bought 3 that didn’t work ). Currently a Wix 42081 in the car, which is dirty, and unavailable new. K&N has nothing that I’ve found.

Have you seen this list of part numbers to cross reference to?

Seems like there is quite a few matches, but might be challenging to find one in stock with my quick search. There are some NOS AC Delco A90CW filters on eBay, but they are pricey.
