Where can I find these plugs that go on the underside of each rocker panel?

LeX2K

About $3 at a Toyota dealer
90950-01327

Or could use some generic rubber plugs from Amazon or even better an auto body supply store. Also used on a bunch of Toyota's like 4Runner, Celica, Corolla if you like to visit salvage yards.

Thanks. Thought about just using a generic plug but the ones on my car seem to be "vented" (to let moisture escape??)

I will try the Toyota deler.

If those are vented they won't stay that way for long they'll get filled with dirt. If you plan on keeping your car for a long time fill the rocker panels with Fluid Film it sloshes around as you drive and displaces moisture. It will leak out through all the seams which is what you want.

My car is 30 years old this month.

Seven of the original plugs are still in place and are in excellent condition as shown by the above picture in my initial post...

I went to the Toyota dealership today. What they showed in their system for part number 90950-01327 did not look like the plugs that my car has.

So I went to the Lexus dealer. In their system, part number 90950-01327 for a SC300 looked like my plugs so I ordered one from them. Cost: $5.18
