Adding A/C to a RHD non A/C car

[Shftr8]

I just picked up a nice RHD touring with no A/C. I am wondering if the evap box would be the same and I just need to add the evap or if a left hand drive box would be the same? Any help from someone with experience in this would be great

Cross reference the part numbers on RealOEM.com. Probably won't get much help here as most people have never dealt with RHD cars.
