Re: [Chrysler300] 64 gauge swing

[" JC Auto Restoration, Inc." <jcauto56@xxxxxxxxxxx>]

Hi Bob,

Actually, the thermal-style gauges which use a voltage limiter were 
introduced in MoPars in the 1959 model year, but only in the Dodge and 
Imperial models.  By 1960 the entire Chrysler Corporation lineup used the 
thermal-style gauges.

We here at JC Auto Restoration offer a solid-state internal voltage limiter 
conversion that effectively solves the drifting gauge syndrome by giving the 
gauges a constant, electronically-controlled output voltage.  This allows a 
more precise calibration of the gauge movements as well.  The cost for this 
voltage limiter conversion is $85, plus an additional $45 per gauge as 
required to calibrate the thermal movement.  All of our electrical 
restoration work is warranted for one year, which is 365 days longer than 
from Chrysler when these parts were available new...

Hope this helps!

Jeff
