[BR3W CITY]

It'll take a cableX if you want to run a gear driven speedo on an ls swap. Otherwise any electric speedo you can find would work. You can even just use a gps if your in a pinch for a short time while finding a more elegant solution.

I chose to make the tach the centerpiece of my dash, so my speedo is a function of the Scangauge II that I have. It small and runs off the ECM, has like 50 functions, one of which is speedo. The display is not large, and is digital only, but its plenty readable from where I sit, and since it can display other stuff and scan the ecm, its a swiss army knife in the cab.

take a look at the "testing lights " video I posted in my build, it shows the scangauge at night, and I have some pictures of it on the dash in the build as well.
