neutral switch and reverse lights

Hey guys ,
Just getting started on a project after being out of this stuff for a while and need a bit of info.
I'm looking for the neutral switch and the reverse light switch on a 75 - 360 ,4 spd Duster.
The Haynes manual is good but doesn't give me locations on these two switches.
The guy I bought it from had bypassed the neutral switch for some reason , and the lights I'm thinking is a switch issue.
