Gotta say I'm happy with my NB top. Thanks for the compliment POS.

Getting a NB top you can install it in an hour.

Getting a new top, you are looking at several hours. You will be drilling out and replacing rivits too. You will also need a new rain rail. (Figure $180 for that)

The 92 has a brittle plastic rain rail. Mazda finally got smart and went to a more durable rubber rain rail on later Miatas. (99 and up IIRC?)

You will want a 99-02 top and frame IIRC which will include a more durable rain rail. I bought mine in flEa-Bay The window is a no zip glass which is a really nice feature and more durable, clearer than a plastic window.

If you still want to replace your top I'd go with Robbins or Cabrio World. One of them makes a no-zip glass as well but I have no first hand or even second hand experience with them.

I live in McKinney if you need help.
