George took a bunch of photos of his fasteners and S30Z bits before he sent them to a plater for reference. He was going to send me the photos so I could make them public / available for reference by all.
I may do the same also anyway with mine, turns out when getting the bolts plated they can't keep them all organised, they just dunk them all into the tank at the same time.
If you're familiar with S30Z's you'll probably recognise where a lot go, which is a good start. The rest you can probably refer to parts manuals etc..some can still be ordered new...
I've seen some people selling parts lots of S30Z bolts for about $50 on eBay etc.. I was thinking of just buying a job lot of bolts like that and getting them re-plated and using my original ones as a reference to sort them once returned. That might be doing thing ass forwards first though..
