It depends on the bore and size of the journals and crankshaft. you need to take it apart first and match up the numbers on the block and the crank to get the bearing sizes.

This is from my 7A-FE rebuild but it's pretty much the same for a 5S only the numbers engraved on the crank are all in the same place and stamped sideways on one of the crankshaft balancers.

to find the size of the main bearings...


for the crankshaft...


there are 5 numbers engraved on the corner of the block (top and bottom)....


that correspond to 5 numbers engraved on the crankshaft itself...



you add the number on the crank to the corresponding number on the block.
no number means 0. so the 01 on the crank pictured combines with the 2 printed on the block to come up with a #3 bearing.
