It is the Vintage Air system. went in like a glove & setting up the controls positions by way of programing was a snap too. I went for the new style compressor as the cost was less ( at the time) than the retro looking one. A sweet system that blows so cold the wife asked me a number of times to turn it down . That never happened with the OEM in my other Bird. I almost forgot to mention you will need spacers & longer bolts on the PS pump mount to make the belts line up right, but that's all you have to modify.
