Hey Buddy,
No one has answered this question, i did a google on it and found filters for everthing except the old style hilborn scoops. Now the question is do you have an original hilborn scoop? There's lot's of after market scoops but most of them have brackets welded inside the scoops for filters, the ones that mount outside the scoop i could not find except for the the bug,bird,buzzard scoops, might have to be made special, if you really want one that bad.
