You can pick up the stock intake lid from Vincent_Doggy-
Linky. Lithia Toyota stocks most of the timing belt and related accessories, and the thermostat part number is 90916-03100, came in the Land Cruiser, Sequoia, and some Tundras with the 4.0 and 4.6 liter V8's, early to mid 2000's models so its readily available in any parts store or Toyota dealership. Also, just for my sake, could you post a picture of the back of the intake runners? Either between cylinders 1 and or or between 3 and 4, there may be a small nipple for a vacuum line sticking down and capped off. If its there, you have a late-spec BEAMS. If not, it's an early spec. There's no difference between them, it's just cool knowing which you have.
You're also going to need a new screen name now.
