need help with connecting rod bearings

[dogdrinkincoffee]

I got minor rod knock and i wanted to change my connecting rod bearings first before anything and i dont know what size to get.12111-53F00 0294 KA24DE STD GRADE 012111-53F01 0294 KA24DE STD GRADE 112111-53F02 0294 Ka24DE STD GRADE 2

what the hell is the difference between grade 0,1,2

Only my 2nd rod knocks and it only knocks at like 2.1k -2.3k rpm.

and at the moment i do not have money to do anything. I can only do this as a cheap fix until i get a swap.

thank you
