车祸卖车后忘记取车牌

疫情期间出门买菜出车祸，车total loss， 所以低价把车卖了。因为第一次卖车没经验，忘记取车牌了，修理厂老板转账给我后，我就直接把title给他了。现在车的所有资料都在他的手上，最近又联系不上他，请问如何处理。NJ MVC 官网上写 “If your vehicle is sold, junked or destroyed and you do not intend to purchase another, you must turn in the registration and plates to the MVC for cancellation.” ， 我现在没有registration and plates在手，如何cancellation. 知道的朋友麻烦说下，谢谢。

plate is destroyed during accident. 有registration没问题的吧
