you will have to change to a turbo tranny to get 23 spline all the way thru. you would be alright with 23 spline in the rear case. you would need a new 23 spline coupler for the adapter and a naw 4.7 gear set that is 23 spline. the reduction box should be alright 21 spline but the rear case gets alot of torque thru the reduction box
