[DeTomaso] Techno question: (second dumb question of the year)Speedo cable

[Asa Jay Laughton]

When I purchased my Pantera years ago now, the drive gear had the tang 
broken off, and the driven right-angle assembly was gone.  I sourced one 
from a kind soul on this list and it was the second item I put on the 
car.  (A new muffler hanger was the first if you must know)
