I emailed ez-down to see if they were going to release a damper for the 1st gen DC at all. Here's the response if anyone is interested.
"Stabilus is looking for a damper that will work on that truck. It needs to be about an inch longer than the one currently in the Tacoma kit.
We do not have a release date on this, but will keep your info on file, and send you an email when we know something more definitive on this.
Thanks for your interest in the product.
So there's still hope for us 1st gen owners that they will come out with one that works pretty soon.
