Hello,

I'm trying to understand the pedigree of the cobra 9K tach contained in the attached. Any help would be appreciated.

Thank you,

Mark

It looks like a poor reproduction of the original.  Just about every detail is different then want came the tach's used on the cars from the factory..

Here is a photo you may find helpful - it appeared on SAAC Forum 1.0 some time ago (I think prior to the crash). I do not recall who posted it, but I do not want to take credit for someone else's work.

These depict the evolution of the face details on Cobra 9000 RPM tachs installed into '66 GT350's, plus a view of the over the counter or service and Cougar versions. I call particular attention to the shape of the white needle - original production versions have a "cricket bat" shape, replacements and repros have a tapered point needle.

Another way to identify an original is to look at the back of the housing. Originals were produced by Faria, which typically placed a purple ink stamp on the back with their manufacturing ID plus a production date. These tachs were also stamped "8 CYL" in large type. There was an accessory 6 cyl version, but these usually have a 6000 RPM range on the face.

Hi Bill,

That is my photo composite of the four tachometers.  I am glad to share.

If I can find, I will post a higher resolution image.

Thanks

Hi Cory,
Thanks for the original post and follow up. The photo I posted was a jfif file which is likely why it wouldn't open. I converted it to jpeg to repost but I see you beat me to it!  :)

Change from top to bottom location I would put it in the very high 600's. Remember not all cars were finished in sequential (Shelby VIN) order and there are allot of replacement ones out there due to issues or thief

It seams there are many of these tach's offered for sale with cut wires.  Makes you wonder if these were stolen back in the day.  It would be much easier to cut wires than try to get under the dash and unplug, especially if you are in a hurry.

In my literature collection I have several dealer work orders for '66 GT350H's that were being returned post lease from Hertz for refurbishment prior to being offered for sale. The most common notation on these was missing tachometers and seat belts.
