Well, Rob isn't a JEGS, or SUMMIT....as for those companies, they will put their nose in the air when it comes to parts for our cars. We are lucky to still have Rob making parts for these cars, as he could easily move on to something else. Anything you do custom for the crossfire isn't going to happen fast. The dual cai, comes as a kit...usually boxed into one pkg...and he is usually meticulous about this...hopefully you get it resolved...but, highly unusual for a Needswings product....
