final drive ratio webpage?

["Evangelos G. Makris" <emakris@hol.gr>]

Some time ago, someone posted a URL where
final drive ratio and speedometer related
data and formulas could be found.

What was that URL?

It seems a local junkyard has two or three
Spridget speedometers (and I thought I had the
only Sprite within a 200 mile radius) and I've
got to know which one to get.
