If you're willing to drive to Plano, I just had my daughter's 98 GT top replaced by:
Dee's Auto Trim
1730 Millard Dr # D
Plano, TX 75074
Phone: (972) 422-7623
Talk to Jody (guy). Quick scheduling and was done in one day. Good workmanship, looks perfect and no leaks. About $1200 for the vinyl replacement. You can get cloth like my Cobra for about $1700. Good luck.
