72 Duster Resurrection

Yes probably. I'd ohm out the wire to the neutral safety switch to eliminate an internal break in the wiring. The neutral safety switch on that year is a multifunction switch. Its used for park and neutral starting, and for turning on the reverse lights. Also make sure you have a good body to engine ground at the firewall. Not having this causes all sorts of weird problems. I think mopar went to this switch about 1968 and continued to use it on all RWD automatic transmissions at least thru the early 1980s. Should look similar to pic below. It will be on the left side of the trans near shifter linkage input to the trans. Put a bucket or pan under it when you swap it out.

I would recommend rock auto for most of what you will need. I use em and they are great. Especially when stuff goes on closeout. Just checked rockauto. They got a neutral safety switch. airtex/wells PN# 9A6 for $6.35. For 1972 duster slant 6 automatic. I try to round up a bunch of stuff i need from em being shipped from the same location so i only get hit with 1 shipping cost. Way cheaper than local stores like vatozone. On this old stuff they would have to special order it anyway.
