Part number is 90541-09080

I cant find this part number in dealership but i found it online, it's from Lexus parts. So I assume Toyota and Lexus is the same company so they shares the same Part #?

Here it is:..

I actually spaced out the rear bump stops (the two on the body, not the hatch) with two oil filter washers on each screw and some silicone paste and I haven't put it to the test but initial impressions is that it helped quite a bit. You could use a rubber washer or the washer type o-ring from a hose. I really hope this at least improves the rattly as hell hatch of mine.
