when moving springs into longitudinal

with a little work , you can fit 295`s in there ...

Not on a Dart you can't. The Darts have 1" less room in the factory tubs than a Barracuda/Duster/Demon/Dart Sport.

The OP has a '72 Dart, and the only way to get a 295 in one of those is a mini-tub or a 3" lift.
