Neutral safety switch

[limegreen70]

I am using a 727 out of a 67 plymouth. It has the single prong NSS. Can I put the later style 3 prong in it and that's it? Or.is there more that needs changed?

More to change, and there is some "discussion." Likely at the least you need the later "roostercomb" inside the trans

Depends what you're putting it in. You may be able to rig up a microswitch on the linkage to cover the reverse light function.

in our 67 the backup light switch is in shifter and NSS is 1 prong/wire. I think the 3 prong switch "includes" the reverse light circuit?
