I want to thank everyone for the help, I was able to fix it. My rack wasn't completely grounded. Special thanks to Hotsho111 who suggested checking out the coupler for ground. I grounded that and then kept working my way up to shaft to see where I could no longer fix a ground. I tried drilling a hole for a tap but the metal was too soft and just kept crumbling. I ended up just running a self tapper to the ground near the vent pull.

I removed the hub, cleaned the contacts and the back of the hub. When I ground the wire coming out of the hub the horn goes off. I thought the Green Black wire was the one grounding the hub? I don't know how I would go about finding another ground to add to make it work. Is the steering rod supposed to be grounded?

Yeah, its making contact. I am going to remove the hub and inspect it. I want to make sure there isn't a protective film over the back of the hub. When I tested that little arm, it was showing 12 volts so it should be grounding the hub. I have owned this Z for over a decade and the horns never worked, it had other wiring issues so I never messed with it. Sadly back then I didn't know alot about cars so most of the work was done by a shop. I have been looking at videos and most setups are using a modern horn that has two connections on the back. There are two connections, one from the hub and the other from the ring adapter that connect. Mine only has 1 connection on the horn button.

Okay got some progress, I can now verify that the problem is at the horn button/ hub side. When I ground the wire coming from the hub the horn sounds. The hub comes with a metal ring where the horn wire can attach but nothing happens when I press the horn.

Thanks, I was able to test that and found out my horn was bad. I bought an aftermarket one and the horn works using that method. Now I need to find out why the Green Black wire is not sending the ground signal. Any ideas on how to test that side?

Good afternoon everyone, would like to get some help in getting my horn to work. I have an aftermarket momo hub and horn button. I have tested the turn signal switch part that touches the back of the hub and it shows 12V. I have the oem relay and an aftermarket one. I have tested both with a powersupply and both click with 12V. The Green Red wire that comes from the fuse panel shows 12V. The Green Black wire that comes from the switch doesn't show anything. The Green wire that goes to the horn doesn't show anything either. I saw that someone else ran into a similar problem, so I ran a ground from the steering rack mount holes to vent opener which seems to be part of the chassis. Am I suppose see 12V on the Green Black wire also? Are there any other tests I can do?

Sorry can't help you out with the value. Not many Zs around Denver too. Sorry for your loss, I hope your insurance gives you a fair deal so you can get into another Z soon

I am surprised this is still available especially with all the extra parts you have. I bet you could get more than your asking price through Bring a Trailer or Ebay.

I have a triple set of 40mm Mikuni PHH for sale. I had them inspected and matched by my local Z expert. Asking 1350 shipped within the US. I also have a Cannon manifold with missing linkage that I can throw in for 1500 shipped.

Lucky you, that looks like Datsun Competition Intake too. Those are datsun comp carbs too if I recall correctly. They have that mirrored U on the top. For those looking I got a set of triple 40s that just need to be inspected and I will have a set of 44s for sale once I drop them off to get rebuilt.
