Conrod bearing/shell

I recently swapped the pistons in my spare 1.3 engine for 1.0 piston.
During the swap out I managed to put a scratch in one of the conrod shell/bearings.
I emailed Nissan and they linked me to this replacement part

When I went to fit it I noticed that the new bearing had a hole thro its centre, which I presume is an oil hole, whereas the old bearing doesn't.
It was identical in shape and size to the old one so I went ahead and fitted it.
I have contacted Nissan and they have assured me that it's the correct part.
I'm due to fit the engine next weekend but now I'm freaking out about the hole!!
Have I been sent the wrong part? What do you recon guys ??

Sorry but the link doesn't seem to work??

the lpg CG,s had an extra hole in the shell and rod, for drip lubing iirc wehey

Thanks Frank.
I just had an email back from Nissan and apparently all rod bearings now come with a hole. They sent me this pic of a batch that has just arrived.
So panic over :)
