your best to do a proper measurement buddy before fitting any bearings into the engine, the different size toyota bearings is to correct for a sloppy tollerance when the crank, rods are made. easier to make bearings with extremely different sizes to get ideal clearance than spend more time making sure the crank is perfect for the bearing.
This is the difference between a standard toyota engine and a performance engine, where the parts are much more reliable for size and you make the engine fit the parts.
