I dont know the answer, but I guess it would depend on if you are replacing your overload leaf with the AAL, and if the AAL is only one leaf, and if it is thicker than your overload. If you ARE keeping your overload also, I guess best way would be to measure your Ubolt and see how much thread you have to play with.
Also, does the AAL come with a new center pin?....Cuz the same thing applies for that (on whether you are pulling or keeping your overload, or if the AAL is thicker than the overload...(which I doubt)).
