Advice on a new window for my conv. top

[Jrock26584]

took me and my dad a whole day to do it. All the local shops were quoting 1000-1200 for top and install so i guess just for the install it will be about 4-500. It was real tight the night we finished. I mean it. It took two people to get the top to lock into place. We let it stretch out overnight and put it out in the sun the next day and it opens and closes like a dream. my old top leaked from the day i bought it (used) and then the rear glass came unglued so i decided just to replace it all. Now when it rains there is like a channel around the bottom of the rear of the top that collects the water and it runs out through a spot under the car. Im not sure if it is supposed to do this or not since my top leaked from the beginning. But there is no water leaking into the floor at all. It is all caught in the channel and dranned away.
