there is no VSS as the speedometers are cable driven. shouldnt have to do anything but regear for the speedo.

The VSS is a green box that was used for the cruise control. I'm not sure of the hookup on the 100 mph speedo. If you don't have cruise, don't worry about it.

As far as regearing, no need to. Nothing changes when changing speedos. Just hook it up and go.

The VSS is the little green box with the optic cable that plugs into the back of the speedo. The speedo cable hooks up the same as on a 85 mph speedo.

As Mike said, it is just a simple replace. The connections are the same and the speedo ratio is the same. The ONLY things different is the font and you would need the VSS to use the cruise. Since you aren't, and are willing to overlook the fonts, it is a simple plug in.
