The speedometer in my SPF has about had it, 5-7 mph off at 65, bounces, and the trip meter is busted.
I'm looking at either a Smith's electronic or Smith's GPS. I'm told my Tremec 600 is already set up for the electronic, although I have not put it up the rac to verify. Any issues with the Smith's electronic speeo.

Has anyone installed a a GPS speedometer. if so what issues have you had.

I would like to keep it a Smith's set up as that is what all the other gauges are, and would like to keep it consistent.
