not sure about the split bearing fitting, I think I remember they do not, someone will know for sure
money better spent on rod upgrade on the 2 and 3 bar, the new men (counter-balanced), the new side-strips, new balls, and silicone...
not cheap to do all this but less than a new used coin-op and you can do it in stages...2 and 3 bar your side first, new men on one side and really you could get away without doing the 3 goalie guys if money is tight, side strips are $25 and can be added any time....balls and silicone should be purchased frist no matter what
have you used anything on the rods while you have had the table? either way, if you get knew men, when you break down the rods clean everything really well
oh, and you can consider adding weight to the table, people will have ideas on that, but weight makes a big playing difference and it is something you should be able to do cheap
