I have the following AC stuff for sale:

New(ie installed but never hooked up) rear evaporato runit for an 86-91
GL(pretty sure the Westy is different) and it has the stock speaker holes
cut.  Originally the gray color, vinyl painted beige.  Boought from Bus
Depot a few years ago.  woould like $150 for it which is WAY below
dealer.  also have the front piece I'd let go for $25.  I also have the air
duct channels, but they suffered a little from the "sky is falling "
syndrome way before I got the van.  Buy both and I'll throw in the rear
side panels which are also beige.  All this came out of a 90 GL.

also have a complete rear AC wiring harness(in case yours got hot and
fried).  I'd like $40 for it.  It does not have the relays with it.  I've
also got some of the hoses, but not sure how to extract them or what to
charge for them.

Have the front condenser coil  which if you didn't need it for AC, just
might make an awesome external oil cooler.  $40 for it

P mail for shipping quotes or other questions.  I'll eventually get this
stuff on ebay, but not for a week or two.  Items located at 50613.
