Reusing rods

I’d reuse the rods. Not sure why if it's an ARP bolt it might be proprietary. But I’d rather reuse than buy again.

If he wants all that extra stuff to balance all it means is that stuff has to stay with that assembly forever. Personally I don’t do that because most people will change something that bolts into an engine at some point. I’ve never had an issue just doing the crank either.
