Would an S4's N/A Door panels fit in the place of an S5 TII's?

 

yes all hard top door panels are inerchangable and will bolt right on, only diff is the material patterns and speaker, s4 has no door speaker( well some models have a round one but in a diff spot)
if u have a t2 make sure the s4 door panel your grabing also has power windows...

 

Apillars covers are different. The warning cluster surround piece is different too. To the OP the door panels will fit but make sure the S4 n/a door panels are from a 7 with power windows.
