As to the part number it's different depending on whether your truck is a VCK20 or VCK21. That info. is on your door sill sticker.

85440-35010 = VCK20 08/92-08/94, various 4-runners 08/88-01/95

85440-34010 = VCK21 08/94-07/98

That information may not be the most up to date or complete.

It's likely that the same valves are on other yota trucks, too, with a different bracket.
