I would almost bet they are the same as the 3/4ton & 1 ton because the 3/4 & 1 ton use the same mounts & they also use a spacer that is about 1/2in wide so the clevis doesn't move side to side. The 4400 springs are 2.5" wide & the 3/4 & 1ton springs are 2" wide. Remove the space they use w/the clevis & you should be able to use that mount with your springs.
