i just got a 72 chevelle....it started fine but i did have to go through all the gears on the column and then put it in park.....now it wont start. I am thinking it is the neutral saftey switch....is it located in the column...or on the tranny? also...my started was making a clicking noise before when i tried to start it...and then nothing....i turn the key and nothing happens? what could this be?
