Hello, Thanks for the info and reply! 

I went to David Kee top loader pages and found this:
A black drive gear with 7 teeth pn C4DZ-17285A  NOT for Tiger
A  pink gear with 6 Teeth pn C5ZZ-17285A  NOT for tiger
A Yellow gear with  7 Teeth  pn DK296-YSG  FOR Tiger
A Brown gear with 8 teeth  pn DK286-BSG FOT Tiger
There are no 6T drive gears for the top loader, at least available anyway.  
With the plethora of driven gears and a pair of drive gears and knowing the 
dire diameter for the revolutions per mile calculation then one should be able 
to come pretty dang close to reality I think.  That 8=980 revs per  mile is a 
high number due to the dinky OEM tire size sold with the cars. I think the 
overall diameter of the Dunlop 5.90 tires was 20.5 inches which would be about 
right for the 980 res per mile. Tires today are larger and a 205 x 15 is 23 
inches or so in diameter and that results in a lower of revs per mile to run 
the speedo. So, the drive and driven gears need to be selected  to get that 
tire back to a pseudo 980 revs per mile.  And the rear gear needs to be added 
in as well if it has been changed. Not a terrifically involved process but 
stuff has to be accounted for in order to get a good reading speedo. Final 
fiddling can be achieved internally to the speedo although I have never ever 
tried that. 

Or purchase a GPS unit, lol. Plug and play....  add power, turn on....

I believe the Tiger is 6 teeth. 7 is the other common size.
Other useful info is the Tiger speedo takes 980 revolutions to rack up 1 mile 
on the odometer. Its printed on the face of the speedo in a really small font.
