I just came across Speedhut's "Speedbox". It is a driver for mechanical speedometers that uses an electronic signal. So, for guys using Tremec, 4L60e transmissions, etc... it looks like you have an option if you want to keep your original gauge.
Speedbox.After some research, it seems that Dakota Digital has a similar device.
Dakota DigitalBoth are listed for slightly under 3 bills, which isn't all that out of line considering what a set of high quality replacement gauges go for, the best part is yo keep it looking stock.
