Datsun S30 Stainless Steel Fastener Kits?

What percentage of the fastener kits go unused?

Good question Bryan. That would depend on what model you are assembling. In my case, building a 240Z, the hardware in the below pic is not needed, although what is left over is mostly commonly used pieces and good to have as spares or to have on hand for other modifications, etc. Anyone building a 260Z or 280Z would only have to look at the labels in my pics to determine what packets are not relevant to their build.
