Rock Auto has a "you send us yours/we rebuild it and return yours to you" option. I'd contact Cardone directly as 1000 miles is nothing.Local stores are out too....no ETA.
Mine is a rebuilt 22-2000, leaking out of RH seal/boot. Has maybe 1000 miles of easy driving on it. They can't replace it with a 22-2000 if they don't have a 22-2000 to replace it with so I'm stuck with a "lifetime warranty" rack that has basically no warranty. They can, however, replace it with a GT/V6 rack which I might do. Having had both, there isn't a big enough difference to justify going out of the way for a Cobra specific rack.
