Hi mate, yes a climate control unit from a pre-facelift (My04-06) McIntosh fitted car is what you need. Hundreds of us have done this exact mod, it is tried and true

You can buy the kit with both the climate control and fascia online for $400 odd. Here's a link to a kit online, to give you an idea of exactly what you need.
