I own a 67 Firebird 400 restomod. The K&N oil filter that I use is one of the few high end filters that will fit in the cars stock location, very tight fit next to frame rail. I have to buy it directly from K&N. The ones off the shelf at local auto parts stores have a black lip around the rim and are 1/16 too long. The one that I purchase directly has a silver lip and fits perfectly (sourced from China, I believe but functionally the same product) I will continue to buy this product as long as it is available.
