Does Parking Brake Release when in gear?

I was checking out some of the interior knobs (exterior lights) and etc on my new to me 1975 Dart Sport. Long story short: I pulled the parking brake level under the dash/instrument panel and, can’t find any parking brake release lever or button... Is it possible the ‘75 Dart Sport’s emergency brakes automatically disengage when shifting out from Park (for reverse or Drive)? I feel like an idiot for asking and, wasn’t able to figure this out in the garage today. Car is on jack stands and has been stored for 20+ years... I wasn’t able to shift into gear but, plan on trying this next time I able. Any thoughts or experience is very welcomed! Thanks!
