I'm sure that 's what the reference to 're-manufacturers assemblies' is all about. The rods need to be precision bored.
This brings us back to the original question posed by Richard, 'what is the bore diameter of the big end to take these shells?'
I would also like to know the answer.

Thanks Dave,
There is more to this saga, on inspecting one con-rod so far, the big end cap joint faces looks to have been ground roughly and on laying the faces on a surface plate, it rocks! Not looking good

I fear more will be revealed tomorrow.

Thanks for all the responses so far
