Re: 68 Chevelle AC???
A lot is different between 68 and 69 factory cars with AC. First the cowl itself is different. Location of the compressor, different pulleys, belts, water pump, wiring etc. I have seen that you can buy repro cowl but unless you are ready for an in depth frame off job you might not want to do that. Easiest way out is to buy after market ac system but even then you are going to have to know which cowl is in the car. Here is a couple pic of my car during my restoration (on going). I have no idea why pics loaded on my PC get rotated when uploaded to this site. Just open the image, save and open with your viewer and rotate them. Best of luck. These are tough cars to do, many one year only parts and design
