In my opinion it isn't wor
In my opinion it isn't worth putting new rubber seals on the top. They are gonna leak anyway. Unless however it is a NEW problem. The top on my 348 leaks. I think the bigger problem is that the windows don't seal properly. The tops on the 348/355 area a bad design. You could try the rubber seal from a 355. They have a little lip, on the edge above the window, that could help. But if the windows don't seal proper it is gonna be wasted money in my opinion. I say just don't drive it in the rain.
Now that I think of it. Last week I saw a fix on TV, on one of the car shows, that they added a filler type stuff behind the rubber trim. What it did was to push the rubber out further, so that when the door was closed it made a tighter seal. I don't remember exactly what it was, but I would give that a try before you spend over a grad on rubber that is gonna leak anyway. Good luck let us know what happens.
