Need some damn help getting the right rod bearings. I got crower rods and called crower and ask what they would reccomend as far as color and size and all the guy told me was "between 1000th and 2000th would be acceptable" i was like WTF is that. I know you have to look at the crank and get the letter and the # on the rods too, but my crank say "c" yet my rods say "x1-x4" so how the hell am i supposed to get the right size??? Thanks in advance.
