The Z-Corn. My 80 Z28.

[80Zcorn]

Managed to fix the clock today.
Look like it is working fine. Actually I have 2 clocks.
I tried the 'spare' one. It worked. Then I tried the one in my cluster (yes, opening the dash again) and it worked too...
Now i have 2 working clocks... Guess I'll sell one.

*The site doesn't let me add a video. But trust me they are working

Back at the days I bought used cluster on eBay since it had the 135 mph and lately I realized that's a v6 cluster (tachometer didn't spin right and yellow line was at 4000) I decided to take the tach from my old original cluster and install it in the used one I bought so I'll have the right tach with a 135 mph speedo. Was easy but very delicate. I also reset my odometer so it will be easy to follow maintenance.
I also thought about fixing the non working clock. Any ideas how to do it?

I lift the car and saw coolant at the rear of the block and pan bottom. Never happened before. Any ideas why? What should I check?

Plus i searched for the oil unit location since i want to connect the oil pressure cluster light, i searched near the filter but what I saw didn't seems like a hole for the unit and then i noticed two more holes at the front of the block that seems like they have no purpose... One of them have a bolt threaded to it but it doesn't seem like it attached to anything. Any directions...?

Finish the car is getting close. Your help helps a lot!

Any instructions on how to reset the odometer? I bought a used 130mph speedo to replace the 85mph one and wanted to match the current mileage.

It is easy but should be delicate. There are some videos on YouTube about it.
Take the cluster off, take the speedo off (2 or 3 bolts from behind).
Gently take the speedo off.
Be super gentle and don't touch the needles - they break easy.
Pull up the nut on the column that hold the odometer mileage wheels side so the column will be free to move.
Then - what i did, not sure if it is the perfect way - carefully with no touching the needle I opened the 2 small flat screws on the speedo panel which allowed me to pull the speedo background (where the mph are written) a little bit without touching the needle but still leave me enough room to wiggle the speedo wheels column/ drive out of its bracket. BE SUPER GENTLE IT'S CRITICAL.

Then you have the drive with the wheels in your hand. There's a thick white paper at the rear side of it probably it's dry but try taking it off with our ripping it. Then you'll just need to play with the metal tabs and wheels until they are at 00000 or the required mileage and line the metal tabs too exactly at the back of it.
It may require force sometimes but not too much force.

An important tip: wear gloves since the printing on the wheel may whipped a little with fingers rubbing it and you don't want the numbers to whip out.

This is how I did it. Not sure it is the right way but it worked....

Hope i helped someone at NastyZ too...
Good luck!

I thought I might reach out to the group to see if anyone has had much success restoring the dash bezel for a 79 Z28.?

 

[80Zcorn]

Your bezel is looking great. What do you want to restore?
I epoxied some cracks in my bezel and cleaned the aluminum cover as best as I could.

Yes on a scale of ten mine is about a 7 or 8 ...but the perfectionist in me is always looking for that ten...I'm also starting to investigate manufacturing them locally as well....either injection molded plastic, 3D plastic printed, or other other....It seems to be a significant challenge for any of the current Resto parts companies to make and was wondering why..the original design in my thoughts is still the best looking design to date in my eye...

 

[80Zcorn]

As for now 7 or 8 out of 10 is fine by me. 10 is a show car...
If I would want to get it to 10 I will just but a new one from the manufacture with the biggest amount of good reviews.
If you saw my whole thread, my car is under restoration for 6 years now, and I decided to go with the "Get it running" method (Thanks freiburger!) Plus, with the cost of shipping and taxes to my location, brining everything to 10 and brand new will be around 100,000$.
At 7 or 8 I just wouldn't bother... But this is me.
I have no experience of working with molded plastic but I do have some experience with 3d printing.
Making 3D printing parts sounds great and I am sure that it will be the industry next step. I'm won't be surprised if in 10-20 years this will be the marked. Any color you want. Carbon? you got it! Want an extra accesories? Special interior lighting? Ashtrey? Whatever? No pronlem!
Just need a crazy car guy with 3d experience that will decide to make the desiging effort and go into the market and not just manufacturing 3d printed parts for extreme cars/ project.
I believe the for the first few that will start it and get a good product with good review they will conquer the market.

I love Road Kill boys, just too much fun and have done a few drag them out of the bush and get em running anyway you can projects myself but my Z28 is a numbers matching car that I ordered from the factory...At this moment I think it is worth looking into the manufacturing process.

I really love their show but some reason few years ago motortrend blocked their service outside of the state and now I can only watch it using VPN.

Well, matching numbers car is a different story, If you are into it I'm sure it worth and investment for you.
