speedo calibration

[WAS <Waschu2@charter.net>]

Hi,


        I mark off 52.8 feet in my driveway, disconnect the speedometer drive 
cable from the speedometer push a paper pointer on the end. Then drive 
the car the 52.8 feet while counting the turns the pointer makes. 
Multiply by 100 and you have the correct calibration of turn per mile 
that you need. If it is different then the number on the speedometer 
face  then someone changed the speedometer, rear end or the overdrive 
with a different ratio unit.
