Hello Vric,I'm sorry to hear about your problem.Shall I assume that your kit is a Tamiya??? If so one option that you might consider is contacting the N. American division of Tamiya.As long as the kit is still in production they will send you a replacemant part (credit card needed).I've done this with a decal sheet in the past and they are fast and easy to deal with.
Hope this helps,good luck.
