MR Norms GSS Supercharger

Hi I'm new to the site have 3 E Body's but have an A body part I'm trying to decide whether or not to sell to fund my TA Challenger restoration. Have a date coded 1971 MR Norms GSS Paxton Supercharger (the box,carb,air filter and all the brackets. Missing the fuel pump but that's available , and the Paxton is not burnt). I know these are pretty rare and most of the time the carb is missing but just trying to get an idea of what it's worth?
