D1-SC F/S

I have a D1-SC procharger that I put in my 68 charger. I went to the track with it now 2 times in five years. It might as well be new because it has only been used on a handful of runs. I am selling my car but the supercharger puts people off thinking that car may have been ragged on so I'm trying to sell the procharger separately. I payed 4500 when I got it five years ago and it just never got used. I'd like to get 3500 for it. That includes the supercharger, the brackets, the 4.25 and 3.75 pulleys, the belts, the air fuel ratio gauge, the K&N Filter, the fuel pump and the fuel pressure regulator. Call 701-870-1228 if you have more questions. Thanks

Standard or reverse?
