Larry,

     I'm one of those who have changed their TD's differential from the stock
5.125:1 gearing to 4.3:1 gears from an MGA.  Obviously, this raises havoc with 
the
speedometer/odometer.  Last fall I had my speedometer refurbished by Margaret
Lucas (really) from  MoMa of Albuquerque [ (505) 766-6661].  She obtained, and
installed, the proper gearing inside of my speedometer to compensate for the
difference.  I highly recommend MoMa's service.  Her email is Momanm@aol.com.
