Spriderfire c-t50 replacement tailcap?

[big juice]

Hey guys I bought this sst50 based light off ebay over a year ago. I had trouble with the light not working correctly(imagine that i know) so I sent the tailcap back to hong kong as instructed by the seller. Well needless to say but I still haven't got a replacement after almost a year. Its just been sitting in my office and figured if nothing else I could find a cap to use it instead of tossing it. Can anyone help me locate a cap or pressure pad to make this work again? I'm new so unabale to post pics but tube at the threads is almost one inch. takes 18650 batts if that helps. thx

Since many import-brands are competitor clones with different visual features, you might be able to use the switch off a Trustfire(TR-1200) or maybe Ultrafire(WF-900). Competitor switches are available on Ebay.
