Don't forget the fan blade.  And if you put in the Fridge Mate fan,
which if you haven't you should (because yours is no doubt worn out
by now -- if it's making little ticking sounds then it definitely is)
remember that it has a larger blade that moves more air.  If you're
doing that, use the existing thermostat, not the one that comes with
the fan.  My website has a little .gif showing how to mod the
original fan bracket.  http://pws.prserv.net/synergy/Vanagon/Fridge.htm
