They're used, The ones that go with the rod with the notch looked like they
had peen marks.
The rods all feel fine on the crankshaft. Nice and smooth, clearances good.

Are the nuts new or used? I would think if they are new they should all

Ok, so I spoke with someone at Van Cafe and here's the scoop.
Yes it would be better if the shop they use always supplied a cosmetically
matched set, but it is not always practical for them to do so. They are
matched by weight and do not have stretch bolts. I'm satisfied with their
explanation. The quality of the machine work / rebush looks great!
Cheers, Tom
