I have been looking for the double bubble rear door seal in the US somewhere. Does anybody know of a supplier?

 

I've been meaning to replace mine too. I get rain/car wash water in side the rear cabin.
I read somewhere that you can insert a 5/8" hose up under the rear door seal to make it protrude out a little more. I measured how much I needed and I think it was a little over 6' of hose.

 

I'de like some more info on the 5/8" hose under the door seal.
My 04 has been apart since last July, and parked nose first down a slight incline.
After we had some snow a couple months ago, the snow sat on the rear bumper a few days until it melted.
But, the interior was dry.
Last weekend, I removed the rear carpet to access the fuel pump, which I removed to syphon out the old gas.
Anyway, the foam under the carpet was wet, and only inside where I have the tape in the picture.
Strangely, the carpet is and was dry, only the foam underneathe was wet. No rust or corrosion, but a small area of paint just wiped off the passenger side wheel well, from the soaked foam.
No mold or mildew, and inside still smells clean.
The door seal looks fine.
Which is also why I think it was the slow melting snow under the spare tire. So standing water against the seal, and the foam sucking it up like a sponge.
There is clothe/foam in the back passenger corner also, which was bone dry, with no water stains.
There was fine dust over all the metal too, with no water marks, no signs of sunroof or rear window leaks.
I'm 99.9% sure the water came under the rear door below the spare tire.
I put the carpet on my basement floor, foam side up, and near the dehumidifier. I soaked some water out with a towel.
I've yet to put it back in, and after several hard rains, still parked facing down hill, everything is still dry inside.
Has anyone else experienced anything similiar?
Thanks for any info.

 

Actually, my door seal is fine, and apparently I'm an idiot.
I checked my carpet today, assuming it would be dry, and it wasn't.
I squeezed the foam between my fingers, but instead of water, it was a very fine oil. Which explains the no smell, mold, mildew, or corrosion.
And when I pressed an old towel against it weeks ago, I then just threw that away.
I remembered when I bought this that the power steering pump was leaking badly.
The previous owner had a metal can of ps fluid in the passenger side rear storage bin...and in a plastic bag, as he said it spilled because the top wasn't on tight.
So, I found a very small damp spot in the carpet...under the storage bin area.
Apparently it leaked through, and that's what ate a small amount of paint off the fender well, but didn't rust it.
It was cold when I originally took the carpet out, and my hands were dirty. What I assumed to be water, was only spilled ps fluid.
That's a relife, and I'm grateful for stupidly overlooking a simple problem. I have no water leaks!!!
Gotta love it.
