No, but the one that comes with the Ford quadrant kit is. Cost is about $40-$41 from Summit or Jegs. Look for M-7553-C302 Service Cable, 1982-95 Mustangs
Ford Adjustable cable from above- notice the end in the upper part of the picture. That is the threaded adjuster shaft.
If you want the whole kit, it is P/N M-7553-B302, Cable and Quadrant kit 1982-95 Mustangs
OK let me ask you this....if they just created a prototype, why the hell would so many people be recommending it to you? Do you even see how retarded that sounds?
The point is, you don't have to be an ass when people try to help you. The big supersize smart ass response wasn't necessary. The cable in the link i posted IS adjustable, whether or not they have it in stock is another issue but they DO sell it, and it is a modified OEM Ford cable just like i said in my first post. They've been selling that kit for as long as i've been a member of this forum, probably longer. Whatever they're telling you on the phone is complete BS or YOU are asking the wrong question.
A simple search on this forum will show you people have been using them at least as far back as 2004.
even if you posted that the T56 bellhousing requires an adjustable clutch cable , the responce would still be the same. We posted the best options out there that have proven themselves to be the best option for our cars, if you want a list of junk cables that snap and bind we can provide those too but that wouldn't be like the members on here to recommend a crappy part that will fail. The Ford cable & steeda are highly regarded, from the way it looks in this post those are your options.
Anyone have pics of the Steeda cable? I wouldn't be surprised if that's a Ford cable as well. Another note that i'll add just because i just thought about it, is if you have full length headers or some other situation where the '87-93 cable is rubbing or something, you can use the '94-95 cable as they're a little longer and help to clear headers if you have an issue.
Oh man, and the icing on the cake, i just asked my buddy (fordfan89 on here) who has a T56 in his GT, and guess what cable he's using?? A stock replacement with an aluminum quadrant and firewall adjuster.
