1967-1972 Gauge retrofitting for Tach

Click images for Hi-Res Image...

Started with a spare gauge gluster, and modify the lense and metal plate, by removing the section in the middle...

Next, I used a clock from a mid '70 Chevy Truck and mounted it in one of the unused slots. Also had to drill a hole in the lense for the clock adjuster....

I also used a Volt Meter from the same truck to replace the Ammeter

Here's the cluster without the tach...

And the final cluster with the old Sun tach that fit nicely in the hole
