Yes, I was able to source what appears to be a door seal for a Sky Rocket. It has been installed and works well. I asked the company that sourced it if I could provide their contact info on this forum so that others could get one and they said "no", that it was a one time "thing" and that they would not be sourcing anymore. Sorry.
What I would suggest is that you contact the aftermarket door seal companies and bug them to source one for you. You will probably stumble upon the same company I found. They were adamant that they didn't want me sharing their contact information because they weren't interested in procuring anymore. I know that doesn't help but I'm trying to honor my commitment to them and help you indirectly.
