Rallye Gauge Replacement 1970 Mopar

Replacing the gauges and gauge face components on this 1970 Dodge Charger R/T was a necessary upgrade. None of the gauges were reliably operating, the dimmer switch was non-functional and there was an assortment of  "custom" additions to the dash area and critical no heater box, radio, radio faceplace, glove box etc. Needless to say it was a mess. 


In this case we removed the entire dash, steering column etc as the car was undergoing a complete restoration. This makes it much easier to get the gauge cluster out. You can remove it from the front of the dash if you need to but we'd recommend masking off the painted areas and dropping the steering column. Small hands help reach all the connections too!

OER was the source for new replacement gauges in this situation. We did have issues with functionality of a couple of them after installation and had to replace the new gauges a 2nd time before the dash was working correctly. 

The circuit board at the back of the cluster was also replaced. These often cause issues with gauge malfunction if a car has sat in a non-climate controlled storage area for any period of time.

Gauge bezel replacement

Mini torch and a flat screwdriver are used to melt the plastic tabs and secure the gauge face. Be sure to heat the screwdriver and press down until the tab is fully flattened. Do not apply torch flame to the gauge face itself
