Hmm, hard to tell from the wording on those, but what I have might be too far gone to use the repair kit (though their full rebuild service could be an option. Looks like they just have an overlap plate they attach to the motor that the tubes then attach to for better support. I think I remember someone on the forum mentioning another place that did regulator rebuilds, unless it was the same one. My one regulator isn't too bad, though it might be irrelevant as I'd likely have to replace the full length anyway as it broke right where it goes into the guide at the track. The other one I got from the donor door they used to fix my car and the tube on it is broken all over the place and along the length of it.
It always looked like you could potentially replace the tubes with a little careful work, though that's more of a "catastrophic" repair. You'd have to cut the tube out where they glued them into the guides, then drill out the glue and remaining tube pieces and hope to be able to replace it. Seems doable, but could be tough as the plastic ages and has a tendency to crack.
I'll be curious to follow along with your experience and I'll have to check out the YouTube video to get a better idea of what they are doing.
