1966 valiant ignition problem

first thanks to everyone who posted here. @ bill grissom by nothing i mean not a click or anything. the radio plays when ignition is on. but i can jump the solenoid and start the car when ignition is turned on. i just went out and put the car in reverse and tried starting it by jumping the solenoid. it started cranking while in gear. this is leading me to believe that the neutral safety switch is bad. any thoughts on this. i happen to have a nns switch so i will be putting it in regardless. if i'm not mistaken this should be located on the driver side of tranny. it is a 904 tranny automatic with floor shift. any help of location would be helpful. thanks.
