Thanks for the suggestions!!
But I had something in mind like a cross reference based on actual physical size. Such as a grouping by thread size, filter diameter (or gasket diameter), etc. I really don't want to go down to my local auto parts store and take 10 or 15 filters out of the box to compare all of this. I do realize you may have to have the numbers relate to one particular brand but that would be a start.
In other words, I have a 3/4 x 16 thread filter 2.5 inches in diameter and 3.5 inches long (I made this up don't take it as real). What filter is just a little longer, then longer than that or maybe just a hair bigger in diameter, etc?
Are there just not that many different sizes and am I making a mountain out of a mole hill?
