There is no aftermarket cable. The way to find out what it will cost from
the dealer is to call and ask. Good used ones can also be found by the
thousands in wrecking yards.

Not sure if this applies to the 1991 New Yorker you have, but after
looking at a bunch of CC vans in the boneyard (and mine as well) I note
that the "cable" is nothing more than a piece of nylon-fiber type of
"string" that I have seen in fishing shops. Cheap. The K-cars have the
same "cable" too.

But then check with your dealer as to their price. Sometimes the CC price
is worth the PITA factor of crafting a replacement yourself...
