Jesse, I checked high and low and the only thing I found as far as a form goes is in their customer service section. You can go to "Missing Parts" or something and use a pull-down menu to purchase replacement parts for several toys (this might be useful for some of you customizers), but there is no listing for the Obi-Wan JSF anywhere on it.
In the FAQ section, there is an entry for the Obi-Wan JSF in the second pull-down menu under "Star Wars" but when I attempted to select it, the screen it brough up said "0 Entries Found." So who knows what they're doing or not doing.
I ended up sending an email to them making yet another request for a replacement label sheet, supplying a link to the GH article and photo in the process, but who knows if that will do any good. I just hope that everyone is able to get their sheet and put this whole mess behind us.
