What is the timing at idle and at 3,000 RPM? Have you checked the valve lash?

There are a couple of people in the Atlanta area I would trust. If there's someone near you, @Patcon might know. I don't know if the Upstate Z Car Club still exists, but if they do, someone there may know, too.

D'oh! I missed the hint. You know I'll help. It's more a matter of scheduling than anything else.

You aren't giving us much in the way of details here.

That's not how the gauge works. As for an adapter, if you have a mechanical gauge with 1/8 NPT, you need an adapter like this: https://www.amazon.com/Dewhel-Female-Sensor-Adapter-Reducer/dp/B00V5Q6GME and a gauge like this: https://www.amazon.com/dp/B08HRPSJSB

Check with a mechanical gauge.

Or build your own... Right, @Matthew Abate?

I have used these without problems. As for the spades without crimpers, I'm sure you could find some if you searched more, such as this: https://www.amazon.com/PONFY-Connector-Assortment-Insulating-Electrical Vintage Connections has a lot of bullets, too, and I have plenty in my collection. Keep in mind that what you see at Cycle Terminal and Vintage Connections might have been produced at the same plant as the ones I linked from Amazon.

For the bullets: https://www.amazon.com/gp/product/B073GM7WST/ Rings: https://www.amazon.com/gp/product/B08QHZXZ3S Spade: https://www.amazon.com/gp/product/B07VKCCN12

Maybe mineral oil instead of mineral spirits.

The owner of the collection, Randy Jaffe, is a great guy to hang out with. Getting to turn wrenches on a Z and hang out with a great Z friend is a kick arse way to spend the day. The only thing that could have made it better is calling the wife to look for a part you need, and not only does she find it, she delivers it. Wait! That happened, too! That makes it a SUPER kick arse day!

Okay, it wasn't my Z, but I installed a fresh set of Z Therapy carbs on a 72 for a friend.

It doesn't have fingerprint or facial recognition...So I'm good there.

I know. I was considering coming up to visit you.

Do you think @Patcon placed this ad?

Did you go back to them and ask about it? From what I've heard from other people, they stand behind their product.

No problem. One thing I forgot to mention is that the gear ratios of the transmissions are in their respective FSMs. I'm working in the office today so I don't have ready access to my copies at the moment.

I'm definitely not an expert on the subject, but according to https://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/transmission-assembly there are four part numbers for automatic transmissions. Of course, the gear ratios can be found in the FSMs on this site. The 73 FSM was the first that I found with AT section in the FSM. The rear end ratio is the same across all years. I can't think of a reason why there would be external dimension differences that would adversely affect installation. As for tips/tricks advice, I know I have seen a thread here or there on swapping in an automatic either on this site or zcar.com. The only recommendation I can make is to modify the wiring to the solenoid to add the neutral safety switch.

George Carlin was talking about underleg deodorant a LONG time ago.

I actually reached out to Philip a couple of years ago on Linkedin when I had not heard from him in a while. I think @Captain Obvious may have talked on the phone with him, too. I know I miss his presence here, and I really appreciate the fact that he went out of his way to come up to my place when he was in town and showed me a lot about adjusting valves and tuning SUs. I hope he's enjoying his guitars. I'm sure he's doing creative things with them.

The internet doesn't forget.

Well, you might reach out to @zKarsto see if he has any more. He did 7 years ago according to this thread. To remove the broken piece, you can try heating with mapp gas and using an extractor.
