yeah, 88 was the last year for the t tops. however, in my 81, i replaced the weatherseals for the ttops to roof, and ttops to doors, and they haven't leaked a drop since. some say that the t tops make the car weaker, but throw in a pair of subframes and you're set. if you like the t tops look, you can get an 87-88, replace the seals for like $120, and be fine.
