I found a bunch of NOS Toyota parts at a Nissan place here in Guatemala City. I have a few floor mount dimmer switches part #84140-59620 here. These include the rubber boot that goes over the wire connections. $25/ea + shipping
I'm hoping that some folks from the medical team my wife is out with right now can bring them north and mail them. If that happens you should have them by the end of next week.Money just sent.
