Hi Paul

Hope all is well ?

Currently busy rebuilding my RX8 engine high power and need to know what color main bearings I'll need. I've taking the measurements on the eccentric shaft and is as follows:

Front end: 42.957 millimeter (metric)

Rear end: 42.958 millimeter (metric)

As on the parts catalog it doesn't show inner diameter of the bearings.

Your guidance and assistance will be appreciated.

Regards
Barend. De Beer

Typically  the journal clearance  is .002 inches  or 0.002 inch = 0.050 8 millimeter
I assume you are buying something other than Mazda replacement parts.
