That looks like a stock Saleen supercharger (series 2) including the intake so you should be fine. The supercharger saleen used for the series 2 was an eaton M90.
I am not sure where you can find the carb # but in the past Saleen had replacement ones for about $20. Saleen had sent me this which say covers the series 4 supercharger. However, according to Saleen since Exhibit A will list the prior vehicles covered, it would cover previous like EO's and replace them so you should be good for the series 2.
