[V8] Throttle cable Kickdown Switch Q

[Ingo Rautenberg]

Thanks, Jeremy and Dave.  I trust you had a pleasant Thanksgiving too.

My local parts supplier is closer to $70 for the replacement cable  
(not in stock), but that doesn't surprise me considering the $ vs.  
Euro exchange rate at the present time :-/
Haven't decided whether I will try to do the exchange with the cabel  
from the '90 parts car.  Says the cable is the same for 91-94.  So is  
it different from the '90?  I can't really afford to not drive the  
car 'til middle of next week.  Hmm
