AFAIK - The P/N 2984185 Tachometer was initially a 8,000 RPM tachometer with a 6,500 RPM Redline used in at least the 1970 Hemi and 440 Six Pack powered E-Bodies, and maybe others as well. The same part number was later serviced as a 7,000 RPM tachometer with a lower Redline...
Here is a 8,000 RPM version with the 6,500 RPM Redline that was purchased at a Chrysler dealership in about 1981...
Soooooo, my question is What-Is-It-Worth???
I have seen only the later 7,000 RPM versions for sale in the $450 range... any of these 8,000 RPM versions up for sale recently?
Also what is a NOS P/N 2984182 1970 E-Body Rallye Clock worth?
Knowledgeable comments on applications...?
