Very lucky Clock/Tach EBay purchase

[Funky61]

Yes Clarke, that's correct; both gauges are front loaded.

The pic of the strap on the Tach is an incorrect way of mounting, that should not even be viewed as an example of how to mount any of these gauges rather of an example of how not too! If you look at the face of the Tach it completely covers up the bezel looking like a real "cobb job"!

After three years of periodically checking in I finally got a hold of the guy I met at a swap meet, who lives a fews hours away. He's going to make one final showing at the Sunflower Swap Meet, then he's retiring.

I sent him pictures of the dealer installed battery meter and tach. He has the battery meter. He said he has five boxes of tachs, but he has to looks through for the one I'm looking for. He said he has at least one or two with the red football. Anyway, I'm going to make arrangements to meet him at the swap meet.

Question for you guys... Where does the box for the tach install? On the passengerside inner fenderwell? Near the battery regulator (or whatever it's called)?

I suspect there is no "standard" location for the tach transmitter. It was probably just a decision whoever installed it made. In my Dad's Suburban the shop at Sauder-Lygrisse installed it before he took delivery of it. They hid it behind the triangular "wing" on the driver's side that goes from the top of the grille support up to the top of the radiator support.

That is super interesting Ed - thanks for sharing that. All the factory tach transmitters I have ever seen were screwed to the firewall next to the fuse block or mounted to the drivers side inner fender next to the firewall, and in one case screwed to the firewall vertically adjacent to the master cylinder. Never heard of one being mounted out front so far from power and the distributor, but I guess you could certainly do that. just have wires all the way up the inner fender that way is all - if you have window washers you could strap the transmitter wiring to the fluid hoses I guess.

Here are few more photos on how this was mounted. Clock does not work.

OK - so I certainly agree with Bigblockv6 in that these specific guages are somewhat incorrectly mounted in that they do not recess into the guage cluster, but I must say (forgive me bbv6) that if you buy NOS GMC accessory tachs or clocks in the original GMC boxes you will be provided instructions, wiring and these exact straps and clips to mount either of the two exactly as you see them on this set of photos - so these are correctly mounted in terms of the use of the bolt-on U-strap for the tach and two special C-clamps for the clock housing - the reason I say they are still not done entirely correct is because whomever cut this particular cluster did not feel comfortable cutting it according to the instructions and in this case left the guages flush with the face - could have also been a customer choice to have them done this way - who knows - back then it was like I said earlier - preference of the installer. In any case, If I can find where I saved them, I will scan and upload the instruction sheets from my NOS Tach and Clock and show you guys how GMC says it is supposed to be done and hopefully clear up once and for all anyone's confusion on this subject and get us all more in agreement on what is understood to be correct.

Funky61 you're right about the instructions, the old GMC accessory literature mentions that. Prime examples of mounting correctly are 1960HDGMC and GMCNUT whose bezels are cut out for more chrome and gauge face to show, page 18 of the 1966 GMC Owner's Manual has an illustration of this showing the whole dash for purpose of AC controls. I have found another way of making the clock sit more forward by removing the chrome bezel and mounting it in the cluster without it to make the adjustment knob easier to access, I'll post some pics later.

Here are some pics of the Borg/Studebaker clock compared to the GMC/Borg clock

[GMCNUT]

I just bought a factory clock out of a Studebaker Golden Hawk and it was the exact same as the GMC version - mine is not like the one you show on the right, so it might need to be out of the right Studebaker year or model to be the same one used in GMC's.....

[bigblockv6]

Can you send a pic of your clock?
