I have an old Smc meth system with an external pump and single nozzle, I was wondering if anyone knows what size nozzle it has, i dont see any #s on it on the outside, it is still connected to pipe and still works good. I would like to spray more meth into car, i was wondering if the dual nozzle kit from razors would replace and fit and flow more than the single smc .Razors kit is real nice but my old smc is still working, and i realy dont want to spend that much yet, Any help on this thanks
