New holland 575 baler inches or metric main crank bearing

I am rebuilding my 575 and when ordering parts from messicks website, I ran into the problem of deciding whether I need to order the metric or inches main bearing from the gear box crank arm to the plunger crank arm?  My question is how do u tell if you need the metric or inches bearing assembly?  The inches is 265 and the metric is 365 somewhere in there.
