As I posted on another thread. My crank shaft main bearings thrustbearing mainly seems different do I need to use 4g64 bearings instead of the4g63 bearings they are a different part number.

Bearings are the same bro!

Why do they have a different part number then and my 4g64 crank isn't flat on the side looks like the bearing on the side is supposed to fit in a groove but is two big only hits little of the outter edge edge causing it to wear down and fail.

What year is the 4g64 crank out of ? I believe in 98 they did the same split thrust washer to the 4g64 as they did for the 4g63.
