Please note that some of our parts are manufactured by third parties who only do production runs once every 6-9 months. While we do our best to stock these parts we need to manage their inventory carefully. For this reason, some parts are available only to customers who currently own one of our kits, and the prices posted are not valid for buyers who do not own an existing RCR or Superlite kit. If you have any questions or are ready to place an order, please contact us
