What have you guys done for insurance coverage on all the parts and partially completed vehicle while it is being built. Once the vehicle is registered then insurance is straight forward. However, before that we have $50K+ in parts that could be stolen or damaged by fire. I asked my home insurance if it would be covered, they said no. The were not interested in adding it to my policy for extra cost. My insurance broker is finding that this is the case with all the insurance companies they deal with. Has anyone successfully done this?

Thanks for your help
