Frame Mount Shackle Bushings

Does anyone know for certain that the rear spring bushings, the ones that are mounted to the frame, are the same size as the bushings that go in the springs?
I had some NOS spring bushings in the garage and decided to mount them on the rear springs while I have the jeep stripped down to the bare frame. I got the bushing removed from one spring end, can't tell you how much fun that is. After I installed the new bushing into the spring end, I decided to cut the one out of the frame mount and replace it also since I had one left. I started to cut it out and just on a whim, checked the diameter of the old bushing to the new bushing. The old one in the frame looks like it's a fraction bigger around. I stopped there and thought I had better do some research. I replaced the ones on the front springs last year some time but I can't remember if I changed all of them or just on the spring ends. Thanks.

 

On My 1974 cj5 they were all the same.

 

Thanks, I suspected they were, just wanted to get a second opinion before I replace them.

 

Knowing what year and model you are working on would be helpful to know in the future.
‘55-‘75 CJ uses the same bushings in the springs and frame spring mounts.
