I have a gas guage problem in a 67, which I've been working on and think I've got figured out. But something else came up during the debugging. The car is a standard speedo cluster car with only speedo, fuel gauge and idiot lights. It has a set of add-on guages under the dash, so somebody removed the bulbs from the idiot lights to disable them.
But when I had the flashlight under the dash, I can see that the speedo has the "Fuel" warning light that should only be on a guage/tach car.
So either the speedo has been replaced with the wrong one (most likely), or the entire cluster has been changed but somebody stuck the old gas guage back in the tach hole (not as likely).
The cluster housing has an NH sticker on the back of it. Can anyone tell me if that is the code for the standard non-guage cluster, or is it the code for the speedo/tach cluster? If it is the standard cluster, then I just need to change the film in the fuel light hole. If it is for the guage/tach cluster then I probably just need to get a whole correct cluster and start over.
Thanks for any help - Jeff

If I get a chance I will look and see if I can see mine from underneath the dash. Also, you will want to keep that fuel film. I don't think they repop them. Mine is OK but has a few micro cracks in it and I wouldn't mind a better one if you decide to not keep yours.

Not sure if I'm helping but here's my 2 cents.
My 67 is a U17 car (tach and gauges) and my carrier is original. The broadcast code on it is NK. That said, mine is an SS350 car, so I don't know if that code changes with the tach redline or not. For example, my redline is 5.5., but a 327 car will generally have a 5K redline.

Good morning Jeff!!! I have a standard '67 Camaro dash pod in front of me with the basic speedo / fuel guage and idiot lights.. If I can help, where do you want me to look, and, if you'd like a pic. let me know... Ted

NH is a tach dash.

Hi Kurt S!!! I have the 67 cluster housing in front of me... It is the non tach version.. On the back I have the printed circuit with the last two numerics 67.. Prior number(s) alphae are illegible... In the middle of the printed circuit, there is 6290070 and below that is a PED-1... The housing is numbered in the lower left hand corner 6457863. In the lower right hand corner there is a fairly large number "2" imprinted maybe 1/2" tall.. On the top of the metal part of the casing there was a sticker which is gone. I can still see the outline which is maybe 1 inch tall by 3 inches wide..
All the push-in lights have numbers on black plastic as viewed from the rear...
Anywhere else that could help, just ask!!! Ted

So is NH the 5K redline tach cluster and NK the 5.5K tach cluster??
Thanks -

I don't have enough the redlines in front of me.
I know that the NH cluster is black, NK is blue. Both are gauge clusters.
-
Well, I tried to look under my dash until I got gut cramps. I guess some sit ups are in order. My inner housing looks to be blue and my sticker looked like it said NI or NJ. Mine is a 6k tach. Is there something on this in the CRG pages?
-
The color I mention is the dash color.
Maybe yours is NL?
Try taking a pic of it, sometimes that works out a lot better.
-
Kurt, the dash color? I checked mine again and I'm 99% sure it says NL in orange or red letters. Pics won't work under the dash. Maybe if I have to take it out sometime. I'm kind of curious about this, as I think someone put a tach and console in this car. I really need to find a PO to see what came on this car originally. I'm hoping this code could be used to see if the whole pod was changed or if it's a non-tach pod and just had that put in.
-
I looked at the cluster out of my 68, it has an NL code with a 5K tach. Hope this helps, RonM.
-
I don't think the dash code is related to the tach redline, but I need to dig to prove that.
Harvard,
Does the console have rivnuts holding it in place (gotta look at the floorpan to see them)?
-
On midyear ('63-'67) Corvettes, the cluster broadcast code label relates to varying combinations of the speedo (with/without speedwarning), tach redline (5300, 6000, or 6500), and oil pressure gauge (60 vs. 80 psi).
-
On GTO's the code relates to the different components installed as well...
-
Kurt, Yes, but I put them in. The holes had been reamed out and "customized" so I won't ever know if someone drilled the holes or they were there already. My thinking is the console and tach were added. I was trying to see (by this thread) if the whole speedo cluster had been changed or if someone just put a tch where the fuel guage was. If the latter, I would then assume the guage was added. BTW I sent a PM Kurt.
-
Is there a place to find info on what these cluster broadcast codes meant for Camaros? As I go back to a non-tach car, it would really help me to know if I need a whole new cluster or just a fuel gauge instead of tach. My present cluster is dated correctly for my car's build date and I'm sure many of you could appreciate how difficult it would be to get a whole cluster with the right date as opposed to just a fuel gauge.
-
The broadcast code was applied by AC when they built the cluster in its many combinations as-shipped to the plants. All the various permutations of speedometer types and large tachometer redlines and fuel gauge types determined the broadcast code, which was printed on the Broadcast Copy. The center piece was pierced out of the cluster at the plants to add the U16 Tachometer or the U35 Clock, and the plants pierced the holes for the C50 Rear Defogger and the convertible power top switch, so those options weren't part of the coding for the broadcast code applied by AC.

Is there a resource for checking what these numbers mean John, other than a broadcast copy?

I don't have a chart that breaks down the AC code stickers, but someone out there in the hobby probably has one. Those codes are known for midyear ('63-'67) Corvettes due to the large number of Corvette cluster restorers, but the Corvette clusters weren't as complicated as the Camaro clusters.
