SIZE OF 318 EDLEBROCK AIR FILTER

So, I have posted pictures of my 67 Cuda with the 318 and Edelbrock 404 carb.
I was ordering a new (colored) air filter, and ran into an unusual problem - THE WIDTH OF THE 4 INCH FILTER.

Almost all the standard filters, and even Edelbraock ones, are 14 inches wide.
That roughly measured what I saw, but when it came it was slightly wider than the raised edge of the MOPAR Performance filter cover, and would sit up on the upturned edge of the carb filter base!

**So, the filter in place is more like 13 inches across/diameter.
What's the best solution here to keep my MOPAR Performance cover??
Is there such a thing as a 13 x 4 inch filter? I sure can't find one!
