I have a 1965 Monza. Has anyone replaced the clock with a RPM Tachometer.

Here is the exact tachometer I used:

It works very well in the middle of the cluster.

...to expand....

It works very well in the middle of the cluster and it looks "right" in my opinion. You basically just pull out the center cluster and install this unit. Of course, you need to snake a wire from your distributer, along the existing wiring harness, through the rear firewall and then down through the tunnel under the car... and finally up/under/behind your dashboard. There are existing holes with rubber grommets behind the dash where you can run the wire through to where you need it.

For the record, that's the same Tach I used (though I bought it at an O'reilly's) and mounted under my dash when I felt too inexperienced to pop my own dash (you know, inexperienced until 4 days into the ownership of this car).

It works very well and is easy to install.

I think sethracer here is working on an easy way to do this....an adaptor plate for common tachometer sizes.

May want to PM him?

I used a VDO tach in my '66 Monza. I should have used a green LED for a better match.

If you have a block off plate instead of a clock you can cut out the center of the plate to hold an aftermarket tach. No need for a fabricated mount.

True.
But if you think you may ever want to go back to the stock original look, you may be hooped.
Will a used block-off plate be available at that time?
(Just something to keep in mind.)

Is a "special" six cylinder version required, or do the reproduction tachs work? I took a quick look at a couple of Chevelle sites and they all list one tach for all models / engines but looking for confirmation that this is correct.

Thanks.

The after-market one I used had a switch to select the number of cylinders, and worked fine. This was borne out when I took off the after-market tach and replaced it with a "new" stock tach and it appeared to read the same revs at the same rate as the after-market.

Some things are universal about engines.
