Bill they are getting harder to find. The last time I heard of Koni making a batch was 5+ years ago and it was one of those "this is the last run we are making" situations. You could try Cindy at FWD Performance a call (www.fwdperformance.com) it looks like she might have some sets stored away or possibly she can set you up with a used set to rebuild.

If you really can't find anything you can have a generic brand of l-body struts sent in and they can convert them. The advantage there is you can get them valved for a much higher spring rate then the original Konis. I would have to check the exact spring rates on my shelby but we settled on rates around 800 front / 650 rear which is much too stiff for the normal valving. In that respect a cheap used set that need to be rebuilt are an advantage if you find them.
