You could try Tundra Designs, but they're quite expensive. I think DrftFan might be working on a moldbut last I heard he sold his to JesterFX... who... doesn't have the best reputation. Maybe GC5FX? And remember that you can't buy unlicensed things, but these folks might have a way of helping you out ;-)
I traded the original torso mold frankly because there were so many surface flaws that I got tired of painting them after the fact. I made a very nice master which I just painted today. I will be molding it over the summer along with the legs and the cleaned up cowl.
