Your car didn't originally come with a cable so I'm assuming it's aftermarket.
Instead, it came with a rod like the one shown in the AIM drawing below (item number one). These are available from most vendors and you'll need either part number 3909978 for a 2bbl, P/N 3899072 for a 4bbl (first design - 13 13/16" overall length) or P/N 3909981 (second design - 12 31/32" overall length). You'll also need the attaching parts (items three, four, five, six and eight) which are also available from most vendors.
If you want to stick with a cable, you'll have to contact places like Lokar to see what they have.
