nah, you can use the stock latches. i've got a '99 w/ a hardtop for the 90 model.
now, the 2002 (and perhaps some newer model years) had a recall for latches that would eventually fail... so if you didn't get the repalcement latches, it would be a good idea to get them before driving any serious distance w/the hard top on... dont want your $1000 top flying off at speed. (not that you'd want your soft top to do that either, granted... )
