If what you ask is possible, it does not exist in one spot. The A/C system requires different console and dash pieces; similar with the engine.
The way to do this would be to buy a wreck and use all the hardware: case, controls, bracketing, etc. Use as much as you feel comfortable with of these components: compressor, condensor, evap coil, and hoses. Always use a new drier.
There will be all sorts of new parts that you can't buy, but if you could the price from MB would likely be above $3000 maybe a lot above.
