Not handy.
Plug your VSs directly into the speedo drive on the transmission. Run a known distance (i.e. 10mi down the interstate works well). Divide the number of miles driven by the number of miles showing, and that will tell you what ratio you need.
SPeedometer Service in Colorado Springs used to have good prices on adaptors.
