The tree Tom is referring to is probably a dealer only, or wrecker item
as it doesn't wear out like the thermal vacuum switches do. If they
don't wear out the parts stores just won't stock them (no money in it).
If you go this route make sure the brake booster has a one way valve on
it if it doesn't have one already.
