The previous owner should have a builder number that was assigned to them when they bought the kit. You want to get that number and call Vans to let them know that you are the kit owner now. Then you can order any of the plans that would have come with that particular kit. You can also order the plans on a DVD so that you have them handy on your computer. Getting borrowed plans might not have revisions, or changes to parts that are specific to you particular kit. HTH
