At all four corners the tires measure out to 30.75
The center of the axles are approximately 15". The passenger side may be 1/8 shorter, the lighting was bad & the tape was hard to see.
The front frame just behind the bumper is 22.25 on both sides
The frame just behind the front LCA is 16.75
The frame just in front of the rear LCA is 17.25
The frame just in front of the rear crossmember is 19.5
The measurements are consistent on both left and right sides.I also check that the door sills & bumpers are level.
In table form:
Tire height 30.75 15.75
Axle center 15.00 0.00
Front frame 22.25 7.25
Front LCA 16.75 1.75

The second column is using the axle center as the point of reference.
The doors are currently off and the ragtop is hanging on a nearby wall. The front bumper is stock, the rear is a bit heavy as is the storage box behind the rear seat.
