86 vanagon gl

My air conditioner is sagging and I have proped it up with two shower curtan rods.  I feel like tearing it down but I'm sure some of you out there have seen this problem before and may have some suggestions for fixing this problem.  It seems though as gas prices continue to rise that I might need to just get used to the heat as the air conditioner will just reduce the efficiency of an engine that already doesn't get great gas mileage.  Don't get me wrong I love my vanagon and drive it almost every day.
