Undersize big end bearings?

Where or who sells undersize bearings? I need 54.75mm inside dia. which I believe is 1 undersize, I can get standard size easily. Cheers in advance.

Jumping on the phone would seem the quickest way, hunting through VW mag Aust for the numbers for a shop that's close.

Sounds like you need .010" under, after a crank grind?

Sorted!
