HVAC Swap question
 

I have a 2004 Mazda 6 I and was wondering what your thoughts were on swapping the HVAC temperature controls to the same year S model controls. Would it be a straight swap or would it take some customization? I have the Bose 6 Disc CD changer and will be keeping that. Just thinking about swapping out the HVAC controls only. Thanks for your input.
