Sunroof Leak
 

I have done some research on the infamous sunroof leak and I have tried a some remedies but with no luck. I tried cleaning out the drain holes in the sunroof track but I am still getting a leak. Its not so bad when the rain is light but when it is really coming down and for a long time the roof liner gets wet, sun visor gets wet, and it even makes its way down to soak the carpet. All this happens on the passenger side. I was wondering if replacing the rubber gasket that is around the sunroof glass would help? If so, does anyone have a part number, price, and where to get one? I'm starting too think that the drainage holes are just not big enough to take care of all that water and the gasket is not doing its job.
Any advice is appreciated.

Thanks for the link. I did find sunroof weather strip gasket but no part number, price, etc. The hunt continues...
