Is this for a new Avet? I have 3 of my Avets open in front of me and there are only 6 bearings. Is the MXJ that much different than the MXL that it has 2 more bearings? I only have part #7- Spool bearing, #14 spool bearing,#17 brake bearing, #20 brake bearing, and two #24 drive shaft bearings. My reels are older so some have the sealed bearings and some have the blue plates.
