I know this is a common problem. T-tops leaking. But i'm wondering if mine is because of the seals or the cracks in the plastic. When sitting in the car the very front of the t-top plastic piece has a crack in it where the screw is. Oddly enough that is where my t-top leaks but it seems like the water shouldn't even be getting into that plastic piece. Because there is are no cracks on the outside. But my weatherstripping looks fine. But i'm not really sure. Has anyone else had these cracks? Can you buy just the plastic piece or do you have to get all new t-tops?

 

it shouldnt matter the plastic is cracked where a screw is, because like u said its all in the weatherstripping / seal of the t-tops on the outside.

most likely u just need to adjust the t-tops alittle, on the a-pilars in the front and rear u need to remove / move the plastic around to get to the mounting pin holes, 2 bolt per side, it take some time to get them right but well worth it to keep water out.
