Here’s the part# for the weather strip.
1.) 63252-24030 $199.08

2.) 64462-24010 $246.31

Plus 4 - 5 hours of labour at 140 dollars per hour "

I ended up in homedepot buying this stuff : http://www.homedepot.ca/product/sili...t-black/864990 and just taping it to top of the trunk rubber. Used some rubbing alcohol to clean up the existing rubber and just taped it with the skinny side against the edge of the trunk lip. I then used some silicone epoxy and sealed the few edges of loose rubber gasket against the rear window glass and 24 hours later no more leakage. We had very heavy showers last night and i left it outside to soak for almost 5 hours. Upon inspection the trunk area was bone dry.

Give it a try, cost about 30 dollars for the silicone and the weather stripping. Easy to do and quite effective. Plus it doesn't interfere with the top operation and the black weather stripping looks very OEM.
