I own and run an AC shop here in Va. I recently found and purchased an original owner 89 Toyota SR5 Pickup, 22RE, Black Column auto, long bed with 77,000 miles. Original everything, pristine truck that was garaged kept since new and driven very little. Most every option except AC. I purchased an AC kit from bettermadeair.com This kit does not include the idle up kit that I have purchased years back when I have done 3 other installs. They tell me it is no longer available and internet searches are coming up with zero. Didn't know if anyone here has found a source. I will upload pics of the truck soon. It's amazing! Thanks! Dave
