Does anyone have a good clean photo of the back/underside to a tic-toc-tac for a 1968 Olds 350 manual transmission car which would clearly show the mounting brackets/tabs?

 

I wasn't aware there was any difference for a MT car. The wiring harness is different (because of the elimination of the neutral safety switch), but not at the tach. I'm pretty sure the wiring diagram shows the location of the tach lead wire where it comes through the firewall connector (I remember it's brown). I installed the wire that way rather than run a wire straight from the coil through one of the holes in the firewall (which is the way a lot of poeple do it).

 

At this point, I am just looking for a good photo of the mounting bracket/tabs.

 

It mounts the same way the clock, speedo, or gauge does. There are two screws on each side at 4 o'clock and 8 o'clock that goes through the plastic tab mounts on the dash. FWIW you can either loosen the screws and drop the gauge out the back (hard) or remove the screws and GENTLY remove them through the front (easy). It helps to have a butter knife so you don't scuff up the dash pad

Here's a pic of my dash removed with all the gauges installed. The gauge at left is the clock, that's where the tach goes.

 

Thanks Mike. Is the bracket on your clock mounted in the exact same location as on the other two gauges?

 

Jeff,

I'm pretty sure they are. I know the tach is the same as the clock. I know the clock delete is the same too because I have a Mercruiser tach all set up that fits there too.

This pic is from when I was taking my dash out probably 7 years old. I'm taking it apart again right now but I've also got another dash on the shelf so if no one else has responded by tonight I'll take a look

 

Thanks Mike. If you get a chance tonight and can take a hi-res photo of the bracket I'd appreciate it. If you are able to do this, please email the photo to me at jdana24@comcast.net.
