They were pissed on the phone but after calming them down they sent a little cloth bag of dowels. This was 10-12 years ago. As time has gone along, the rods have been better and better but we check every one for size, out of round and taper. About 5% or so now still need some touch-up in the hone to really be right. They almost always measure small when there is an issue so very easy to fix. Haven't had to cut an eagle rod in several years because it was too big. Press fit small ends are particularly tight. There is just no way to install them as delivered. Often have .003"-.004" press fit. That's just too darn tight. You would have to heat the small end to bright blue to get a pin in. That;s not the right way to do it. We hone them to .0016-.0018 press. That works great. Different shops have different methods. Some even press in at room temp. I don't want to move any metal installing wrist pins. Been using Molnar products for 3 years now. Have not had to machine anything. Still check every part though.

Whats the hp range of the majority of engines you build in school shop with students.
