Just as a matter of interest, this is the vacuum operated trunk release Fly and Rock speak of.
Although not correct for all, it lines up with and will mount in A B,C, and E cars.

I put an electric trunk release on my 70 Sport Satellite . . . donor car was a mid 80's Chrysler 5th Ave. You can get everything, switch, wire harness and trunk release (mounts directly where the old "key only" one does) and install with no issues . . .

I have had 69, 70 C bodies - all were vacuum release.

If I recall correctly, several decades back, my father had a 1971 Newport that had a vacuum truck release. I'm positive it was vacuum powered unit, I'm not 100% on the 1971 model year.

Those pics speak volumes. it is interesting to see how Chrysler used different sources of power to activate different devices on a car. Blown away that 4 completely different car lines "could have" used the same trunk latch........but didn't. Maybe they just saw it as a C body thing.
