Question on Dixco HT/x Hood Tach

[dw69z]

My husband and I are currently in search of finding a Dixco Hood Tach for our 1970 Yenko Deuce Nova (Hugger Orange with black stripes), but to no avail. Right now we are gathering parts and plan to start the restoration process in the fall.
In researching online to find this item we found out that that this tach may have possibly have been used for other vehicles. Could someone please verify which cars these tachs came on that matched the ones on the yenko? Or if you have one or know of someone who may have one please point us into the right direction. We would greatly appreciate it.
