I am in the process of finally installing my Propex heater in the rear closet of my 89 Westy, and have the AC plenum and condenser enclosure off.  One of the rear AC blowers is dead and I just spoke with Van Cafe who informed me that the front blower will not work for the rear AC.  I have see it mentioned at several other vendors that the front blower will indeed work in the rear.  Can anyone who has replace a rear AC blower confirm this?  I figure while I have it all apart that it makes sense to replace as many AC o rings as possible.  The previous owner converted the system to 134, but I don't know what else was done with the conversion.  Is there an o ring kit that we like?

Thanks as always,
