240Z: Another update from the Bodyshop

So, today i had to bring the bodyshop some parts to adjust the fitment and panel gabs of some areasy and got the chance to check out the latest progress.
First the outer LH wheel arch got fitted:

At the moment they’re working on reinstalling the OEM rear quarter panel:

And t hey also created and installed those Floor pan reinforcment panels that came on the cars originally:

Now i got some homework: According to the parts manual, the taillight panels are installed with plastic rivets. The upper panel around the trunk lock came without holes. If i look at thetaillight panels the holes seem to be way to big for plastic rivets and i remember that one had metals crews installed. so it was probably a hack-job done by a previous owner. Before we start to drill holes, i’d like to know the original hole size both in the taillight panel and the trunk lock panel. can anybody help me with these numbers? It would be highly appreciated, so we can get this car back to Factory specification.
