I have an 85� Westy with dealer installed A/C and rust in the rear left corner panel.  In order to make sure I get rid of all the rust I want to remove the rear cabinet, which means (I think) taking out the center shelf with the evaporator.  I have not been able to find guidance on removing the evaporator unit.  Would anyone on the list know where to find instructions for this?  If you have done this, any advice for a novice? Thanks DavidWheaton, IL
