I’m restoring a new 240Z since my last one was rear-ended while stopped at a high rate of speed. I will not tell you how fast since everyone just tells me how lucky I was. My current 240Z suffers from over tightening of bolts, and various fasteners from the former owners, and some non-matching bolts. Does anyone know of a company that is selling complete original looking bolt sets? I do not want the stainless steel I like the Cad look under the hood, the 240z engine compartment when restored properly is one of the nicest look factory original engine compartments in history.

I'm still looking for the fasteners does anyone have any ideas

As far as I know there is nobody selling either partial or complete bolt kist in anything other then SS. What you'll want to look for if going for a stock look is metric fasteners in the J.I.S standard which have smaller heads than the SAE ot DIN standard. The biggest challenge will be finding them in yellow chromate color. That said, you could always find the bolts you want, use a 50/50 mix of muriatic acid and distilled water to remove the plating, and then have them replated in the finish you want.

Note: I found a post which suggested that acid stripping hardened bolts can cause "hydrogen embrittlement", but I cannot speak to this one way or the other. This is the process I used so hopefully this will not be an issue for me at some inopportune moment. My suggestion, and what I did was carefully monitor the stripping and don't leave the fasteners in any longer than you have to.

Talk to Eiji at Datsun Spirit, he has engine bolt kits in the yellow zinc coating, I bought a set last year, like you said, they really dress up the engine.
