Going through some boxes that hadn't been opened since we moved and I found 4 brand new Racor filters with both gaskets still in original wrapping, two of them are R24S and two of them are R26S.  They both fit the R220 housing that most Catalina 36's and 34's used.  The R26 is an inch or so longer than the R24 so has more filtering capacity.

I'd like to sell them all at once or at worst in pairs to cut down shipping hassles and will sell all 4 for $60US plus shipping.  If interested shoot me an email -  bud(at)delaroux.ca.
