I could be wrong but I dont think Better Bodies carry backdated longhood RSR parts. They mainly have aftermarket pieces like Strosek and such. If your going classic long hood wide body RSR look then I recommend GT Racing. I'm pretty sure they even have the long hood that will work with your existing hood latch. Talk to Joel, he is a stand up guy and very helpful.
