If the car is sitting on all 4 wheels and one t bar is fully loose then something else is keeping it up.
Put a jack under the loose t bar lower control arm and jack it up.
If the car raises them either it is at full bump and hitting the up bump stop or something is seized
Assuming your shop floor is relatively flat you could test this theory out by supporting the body on jack stands, if it is twisted it will show up.
I have a 67 dart stripped down and one of 4 jack stands needed shimming. Might be my shop floor cause it was only a fraction of an inch.
If it was...
I had a door mechanism on my front door of my house.
Over time the part that retracts the bolt had worn down (worn a grove) and the lever got harder and harder to open the door.
To the point it would no longer open.
Thoughts...
The pin on the back of the outside button might be worn down...
Did this just start happening or has it been getting harder to open as time has gone by?
Have you changed anything in the door?
If you push in, pull out ,lift up or down on the door while pushing the outside button does that change how the door opens from the outside?

155 x 14 tire
Also sits flat in the well.
BUT it is just under 24" OD and the 245 x 60 15 is 26.57.
If used on a suregrip the clutches will be doing a lot of slipping to go straight

Steve,
Do you have suregrip?
If so be sure whatever tire rim combo you get is the same outside diameter as your rear tires.
Unless a 14" rim won't fit your brakes the rim / tire size is immaterial as long as the outside diameter of the tire is the same as your rear.
Here are photos and dimensions from my 67 Dart OEM link and the part number of the OEM repo links installed.
If your OEM sway bar has these type of mounts to the frame
and looks like this
the links are probably the same as 67.
Approximate center between bushings 4.5"
