to grind or no TR2crank 6.26.0.3; VDF: 6.26.0.12; host: imx2.tcd.ie)

With the crank all polished up, not requiring a grind. I am in a 
position of using NOS Mains std.bearings I have acquired, but for the 
big ends (rod) I have NOS 10thou, I cannot seem to locate any tri 
metal bearings from the usual suppliers. Should I have the journals 
reduced to match my NOS set, or is it better to leave well enough 
alone and go with the available bearings.
