Unlike U.S trannys, there is only one speedo gear known for inside the ZF, 
outputting to the right-angle drive and the cable. To correct for giant wheels & 
tires etc, you'll need a conversion box from a good speedo shop, or to 
convert the Pantera to a programmable electronic speedo. Owners have done both and 
the 91-93 Pantera 200/SI had an electronic converter attached to the ZF 
right-angle drive and an electronic speedometer as-stock (no cable at all). Wilkinson 
whould be your source for the factory stuff. The yellow GT5S clone I worked 
on a year ago had a mechanical converter box for its 17" wheels- from Hall, I 
suspect. It was about the size of a matchbox with a short cable driving it and 
the stock cable driving from the converter to the speedometer. Good luck- J
