I was looking to add a temperature gauge and tachometer to my 69 442. I saw a hybrid instrumentation system that has everything upgraded that looks like it mounts behind the dash to give the original appearance. I found it in OPG magazine. Has anyone seen or used these gauges? They look nice, I was looking for recommendations

 

Not sure which ones you are referring to.
The rally pack set I see on their website are 70-72 (silver center disk) and won’t fit 68-69,
even though they list them as 68-72.

I remember seeing some on their site for 68-69 some time ago.

 

The easiest and most economical way to upgrade is to ad a 3 gauge (oil pressure, temp, volts) cluster and a separate tach to your car.
