I should be getting the one I bought in a couple of days. I can compare the two. I barely “bent” it so hopefully I didnt mess it up too bad. As long as the temp is not pegged and the oil pressure doesnt read zero its a win!

Good news! It is fixed. I used 1000 grit sandpaper on the contacts and slightly bent the metal arm. Works as expected. I knew there had to be a way to fix it. Thanks for all the help guys. Keep knocking the finishing tasks off the list.

If you need more pics let me know. I had to remove the compressor to fix the front frame rail. Now I am debating if I go back to R12 or upgrade. One more thing on the list

Does this help? Mine is a 78 280z

Thanks Steve, I bought one on ebay. I know nothing about how these work but I am extremely curious so I opened it up. It seems pretty straight forward though. How can I tell which part failed? Is there a way to bench test it? Like I said, I am just curious and love to see how things work. So it's all I can think about right now! ha!

I pulled the gauge and I do have power from the dash harness. Since the issues resides at the gauge is there a way to fix the voltage regulator? Or wire a new one into the circuit. Or do I need to replace the gauge?

Last night I was driving and the gauges started working again - sort of. They weren't consistent as they moved back and forth. Do you think it still has something to do with the regulator and I have to pull the gauge?

which one of the test samples did you finally choose?

I know this has been covered many times. However, I thought I would post to help others. I repainted my tail light rear panels this weekend - 1978 280z. I am very happy with the outcome. I know this may not suffice for the purists. I did an awful sanding job and I will have to go back and re-do it at some point. Here is what I used SEM 39033 Charcoal Trim SEM 13023 Low Luster Clear Color Krylon K01010A07 Premium Metallic Spray

finally got around to testing the nubbins. They are close, not deep enough for the spring though

Got my nubbins!! They look good. Have a major issue though. My wife threw away my springs. WTF!!!!!????? I have no words. Anyone know where I can get these or do I need to find someone to manufacture springs. I found this company - https://www.jamesspring.com/our-capabilities/compression-springs/

Those come from the c6 block right?

Hi guys, I have a 78 280z. About a month ago the temp/oil gauges were drift back and forth together in unison from left to right. Now they do not work at all. What would have caused this? Before I start ripping out gauges I want a better understanding of what I am looking for. IMG_4406 (1).mp4

I am picking up the part this week. If it works are there a lot of people who could use them

never mind on the washer button. I forgot to put a piece back. Could not get the brass nubbin today. Most likely friday

The machine shop made me a sample. Going to pick it up today! Stupid question? How do you keep the washer button from falling out? I cant see how it connects in other than that little tab.

I just sent over pics and dimensions to a machine shop. Do you think brass is the best metal to use? For reference here are measurements.

@Captain Obvious Ha! Nubbin business! I will message you directly. I am also talking to a machine shop today to see what they can do

Wondering if I try and find a machine shop

what about using some epoxy on the bad one to reform the top? Do you think that could work?

i have access to a 3d printer. Do you think that might work?

@SteveJ I have digital calipers

I was having issues with my headlights where they would only turn on if I played with the knob and moved it back and forth in small increments. I took apart the switch and cleaned up the corrosion. One of my springs with the plastic tips that push the rockers looks melted or worn. I am assuming this is no longer a part I can get. Do I need the plastic piece on top of the spring or can I use the spring without it? Is there anything I can swap the plastic piece with that could work as a fix?

Sounds like I have more fun ahead of me! I think I need start with the headlight switch. It is a little flaky. I have to turn it using slight adjustments to get the headlights to turn on.
