I had a 1991 Stang LX that I removed the spare tire from and put a 12 into. I have sence traded up. Now have a 1995 T-Bird LX V8. I am thinking of doing the same thing. With wieght worries on the track using one side for a box vise six sides. I figure I might save some much needed space. The only problem, I couldn't ever get the box in that stang to seal. Suer it hit all right. But the car was kinda a beater so I did't really care. The bird is my baby, and I don't want the throw 1.5 inch screws down in to the metal. Do any of you all have a thought on how I could seal it?
