A10 con rods

[JulianS]

I think to use those rods is  risk. With what has been seen and no known history I would not let them near my A10 engine.

It also looks like they are both drilled with oil holes, only the drive side rod was so drilled.

If a rod had had such a hard life so as to cause the rod to stretch there would surly be noticeable ovality of the big end and a very worn small end.  I know it would only be by a small amount but do the number and letters how any sign of distortion when compared.
But, as Julian says, best not to take the chance and feel sorry for whoever has the other odd pair.
