Rustys 4.5" kit

I am aquiring a Rustys 4.5" AAL kit for a pretty good price. I was wondering if the greasable shackle that comes with this kit is Rustys .75" or his 1.5" shackle. I know its AAL kit but my leaves only have 38,000 miles on them and they are not sagged.

when i got my kit from him i didnt get a shackle...
