I have to fit new bearing sells and there seems to be quite a few part numbers floating around - some seem for engines up to 1955....Draganfly lists a number 67-320 as standard, 67-244/5/6 etc as +10/20 etc.... others list them as 67-320 A/B/C for the various undersizes. Have also seen 67-0341???
I presume one avoids the cheaper ones by MCA and others, costing between 24 and 34 pounds a set?
Since I need +0.010" I suggest I need 67-320A or Draganfly's 67-244 for my 1959 small journal crank??
Before I order let me ask the experts to get it right!
