Hi I'm new to all this but hopefully someone knows a bit about differentials Im looking for differentials for my truck and I found a Bronco same year and body style but my question is whether or not you can put differentials from an automatic in a manual or vice versa? Thanks

 

Definitely. F150 and Bronco are the same animal, and the diffs don't care what you've got to turn them with.
2wd and 4x4 have different width rear springs, but that's about it, and it doesn't affect the diff.

 

gear ratio may be different, should be tag on bolt on 3rd member that tells ratio
