Hopefully this air filter chart will aid your search. You can take it to your local parts house, swap meet and keep it handy when you are on ebay.

This research was done using a major brand filter catalog from the 70s and utilizing it's extensive cross referencing in the back of the catalog. I have relied entirely on this catalog for accuracy so this research is as accurate as the source book that provided it.

Also you can see that the chart is not complete. If you find errors or have additions please send them to the 300 Club editor and we will update the chart as needed. It would be great to eventually have numbers in all of the spaces.
