They did not have different speedos for the o/d cars.  All cars I've seen (68 
- 74) used the 1280 series speedo.  In 1975, the o/d cars went to 1000 tpm 
(turns per minute) due to the slight changes in the o/d gearing.  I suspect 
the change in o/d gearing was due to the fact that the plastic gears on the 
1280 units wore out fairly quickly.    But, 1975 - 1976 cars (non-o/d) used 
the 1280.  And I have seen 1975 with 1280 and o/d.  There was some weird 
stuff going on in 75 & 76.  It all depends upon the o/d unit.  Typically, 
black label units were 1280 and blue label units were 1000.  From 1977 up, 
all cars (non-o/d & o/d) used 1000 tpm.  Make sense?
