Rallye dash gauge upgrade

I use the stock gauges on the rallye dash , so far they are very accurate as far as fuel tank , oil pressure and temp . Fuel gauge works perfectly , when it is on empty I know I have less than 1 gallon and I better find a station in the next 15-20 miles . Had the fuel , speedo and ammeter done by http://premiumdashdecals.com/
and they have worked perfectly for the last 4 years .
