$100, prefer pick up; but can ship. This unit is very solid; the system currently has a Cat by-pass pipe in line. There is a new Cat Converter still in the box. I used it once when the '75 was still on smog in California.
Two bungs: one for the original CAT sensor and a second for an O2 sensor. Both can be plugged or used.
Chrome 911 tip. I also have the hanger and will throw in two air-guides
