A note about Cherokee disc brake swaps

Are your axles original A body axles(27 7/8"?) or are they 28"?

If my eyes do not deceive me in my measurement is correct it is 27 7/8s" photos below. I was reccomended Scarebird for a bracket kit, link is below. So if that covers the bracket, would that work with the 07' liberty rear disc parts?
