I have two older Lew's BBXLM bait casting fishing reels. The fishing reels do not free spool very well. The spool rides on two oilless bushings. Part numbers are P306183 and P306184. I would like to remove the oilless bushings and replace them with ball bearings. Is this possible? Can you tell me the size (three measurements) for each of the ball bearings ? I need to know their sizes so I can replace the oilless bushings with ball bearings. I am really desperate to fix this problem as the reels are not usable as is. Thank You.
