Leaf spring mounting pads?

[Chris86ranger]

Are they all the same distance apart from the different years? I know the axle length varies, just not sure of the mounting pads.

Ranger is all the same leaf spring spacing from '83-'11, Explorer is same spacing but they are spring under instead of over, and Bronco II is different than either of those just for good measure
