There were 2 undersizes of main bearing journal 1st undersize 59.713-59.726mm, 2nd undersize 59.459-59.472 from Paul Mayo workshop manual. Shell bearings as Brian said.

I asked for the same, but although I'm the one paying the bills untill now heard nothing....will be settled with the next bill (not!!!!) and then I'll inform you all!
