are all main bearing the same or not? i took the crank out to the machine shop and they lost the main bearing. now i forgot to order them. honda said they are all different. i need help fast please

 

They are all different. Check the letters stamped on the block. I dunno if the numbers are in the same place on all Honda blocks. Just write down the letters and take them to Honda. They should have all the info in a service manual.
