Air conditioning options?

So I recently picked up a low mile '70 Swinger with a 198slant A904 and backed up by an 8.75 with 3.55s. It's a super great driver and it is my new daily. I absolutely love it! However, with summer coming into full swing, the heat and humidity is staring I get rough at times. All my buddies are recommending putting air conditioning on it.

So are there any after market AC kits available for it?
