Sure. We've contracted with a local company who has the ability to "repair" the GT Speedo and Tach. As everyone here should know, all of the smaller gauges with re-designed innards (servo core versus air core) are available through AutoMeter at a very reasonable price. However, Ford/Autometer never came to an agreement to re-manufacture the speedo or tach. As such, purchasing a new speedo or tach from Ford is possible at a cost of about $1000 (ea), but they have the same internal design as the original gauges and therefore the same susceptibility to failure.
So, we have been working to replace the innards (I think that's a Southern term) for both the Tach and Speedo. Now for some candid facts...
We have done ~20 speedos and tachs in the past 6 months or so. When they work, they work - and we have had NO failures. (Keep in mind, this is hardly statistically significant with such a small sample - but the air cores are being replaced with servo cores so we are fully expecting this to be a permanent fix.) BUT, we've had a couple - literally 2, repaired gauges be dead on arrival. We've taken both of these back, re-replaced the innards and they have worked... with no additional cost - save the big pain in the ass to install/remove the gauge twice.... which is simply unacceptable. As such, we now have inserted a new step in the process. The company that does the innards replacement for us can & does perform rudimentary testing to make sure the gauge sweeps, etc. But, they do not have the expensive equipment to replicate the signal from the GT Gauge Control Module. Our added step is that newly repaired gauges will be shipped to a company that DOES have the right test equipment and each repaired gauge will be tested with a GT signal to insure it is good before being returned to the customer.
