If anyone else is interested in staying with the stock look, I just spoke with Redline Gauges in CA and they said they can replace the speedo internals with autometer electronic parts for around $200. They also said that they can modify a factory tach to read 7k RPM and make it look completely stock for a few hundred more
. He also mentioned converting the ammeter to voltage output.
The only downside is the 8 week turnaround time, but I suppose I could get by with my Torque app for that.
I am also getting a quote from Classic Instruments, I'll let you know what they say.
Either way, this should be a good bit cheaper AND I get to keep the stockers
