Beat me to the punch. I managed to find the thread and came to the same conclusion. That said, with the electronic version also being NLA it does appear I can refurbish it.The later electronic version can be modified as you describe. The gear driven one cannot. The late electronic version will function in place of the early mechanical one but they are both nla new. The one I posted above is used I got just for testing but they are available new for less than the used Toyota ones sell for, if you can find one.
