In the list archives this has been talked about before and it's claimed to
have been done with good results by just doing it (buy the kit & follow the
directions), then again you'll find those who say it's not simple &
everything needs to be changed.
My list of AC related vanagon posts is on my other computer...

I have to admit that doing repairs that are not necessary (let alone
modifications) while on the road doesn't leave me with a comfortable
feeling.
FWIW ice water & a misting bottle can work wonders in the dry heat our west.
Good luck!
