When putting pistons on rods...

i read about the larger chamfer on the rods, but i couldnt really tell the difference between either side of the rod. anyone have pics? the good part is, the old piston and rod assembly is still together (i needa put new pistons on the old rods). so if i do it one at a time im sure i can get it matched up ok. The thing is, i think the motor was previously rebuilt so i wanna make sure the previous builder put it together right!

thanks for all the info though
