Those are very cool tach's I've only seen a couple in 66 442's doesn't seem to be a bad price so far. Joe

1966 only, rare even when new, and replaced mid-year by the in-dash Rally Pac.

I'm pretty sure the tach was available through out the model run. The rally pac was another option.

my car has Tach only
no rally pack

stan 65 cutlass

could you get the tach in console as well? or was that 64 65 only, vacuum gauge was in the console as well

joe_padavano

64-65 only, where it was automatically included with RPO D55 console. For 1966, RPO U15 was the sidewinder tack. Many folks have installed the 64-65 tach on 66-up consoles.

When was the moto minder vacuum gauge in all that?

66-3X2 442

vacuum gauge was 66 only

U16 was the tach, and it came on most W30s afaik; a couple had the rally pack option instead.

When I restored my 66 years ago, the windings in the dash tach were fried. I was able to stuff the guts from a modern tach into the housing. I glued the original hand on to the new unit. It works and looks original. The light even works.

Very nice!

Thanks Walt!

How hard are these to come by? I was thinking of adding one to my 66.

tru-blue 442

66 only and you don't see them up for sale very often. The one above sold for over $700.

What do they typically go for in working shape?

My car must have been ordered by the dealer. It has the tach in combination with boring bench seat, column shift two speed automatic.
No other instruments except gas gauge. The bench seats and two speed are being exchanged for buckets, 4 speed and console.

Sidewinder sold for $719.00. Nice.

There were no other instruments offered on the 1966 cars until the Rally Pac came out in May, and with the Rally Pac you didn't get the sidewinder tach. Column shift was standard if you ordered an automatic, even with buckets. You had to pay extra for the floor shifter and console.

I've never seen a 66 with the Rally Pack.
Anyone here have one?

I have a set for a 67 but always thought it was incorrect for the 66.

joe_padavano

It was first offered about May 1966, so pretty late in the model year. This Service Guild reprint also supports that it was available on 66 and 67 cars.

I have that rpm tach on mine as well, I'm missing the clock center piece on the right though and what is the tach just forward of the shifter? Also what is the switch above the stereo for? I dont have either of those.

joe_padavano

The "tach" on the console is a vacuum gauge. The switch on the dash could be for the convertible top or for a power antenna.

tru-blue 442

Joe nailed it. The switch on mine is for the convertible top.

joe_padavano

For the 1966-67 model years, there were three options that required switches there, power top, power antenna, and power back window on the wagons. Any given car could have up to two of the three, so depending on the options you could have none, one, or two switches. The switches all looked alike. A convertible or wagon with power antenna would have dual switches.

Lonnies Performance

What is the rarity of a rear blower/defogger option for a 66-67 cutlass/442 ?
I think the switch went in this location also.

Koda

Lonnie is correct. A hardtop with rear defrost and power antenna would have two switches. It was convert top / wagon glass / rear def for one switch and power antenna for the other. The dash always has holes for two switches; the badge was moved to the right a space or two and tiny new holes made for the pins of it.

Awesome thank you.
