Transfer case

[geeps1]

I have a 95 f-150 with push button 4x4 and would like to know if a t-case from a similar year but floor shifted will work , If so other than cutting a hole in the floor what other mods are required ?? Also the truck has a 4in susp lift(i tried to post pic but could`nt for some reason) and the coils have "sagged" over the last 2 years so i bought some DAYSTAR coil spacers, will they work with aftermarket springs ?????
