I'm about to start this job, and just wanted to share something that might be helpful to others thinking about it.
If you go to
Car-Part.com--Used Auto Parts Market and search for 98 land cruiser, and pick "a/c heater controls" in the drop down menu, you will find a ton of them for sale from various junkyards around the country for under $150. It was very easy for me to get one with the pigtails cut out and shipped to me in a few days for a LOT less than what people on ebay or on here are trying to charge.
