I found a set of solenoids on a 88 Toyota 4wd van that were used to actuate its push button 4wd. They used slightly larger vacuum hoses but I was able massage them into the factory hoses. They also were larger in body size so only one could fit ine the stock bracket, the other got the zip tie treatment. Best part is that the colors are the same and the electrical connectors the same. Shifts in and out of 4wd almost instantaneously, I don't remember the stock solenoids ever being that fast when they did work. The 4wd van is pretty cool and worth checking out for fun in the junkyard. Lots of useful? stuff there.
