Ah yes - that would help - here goes:
The new motor is listed as 19 tooth/57/4.25/series - up to 18 mph / 48volt (from D&D motor systems)
The new controller is a 700 amp (ITS) non-programmable (with notes: short housing)
The new solenoid is a HD 36 volt, 400 amp continuous current, 800 amp inrush current, used with 500-650 amp controllers.
