Will Aftermarket (non-Mazda) NA/NB hardtop fit a Mazda Miata NB (1999-2005 US model years)?

Short answer: Yes, with extra parts or work. Limited

Yes, with extra parts or work: Aftermarket tops are made to the shared 1990-2005 shape, so they sit on an NB, but the Miata.net FAQ says most (perhaps all) have the old-style front latches and an NA-style defroster plug.

Details

Aftermarket tops are made to the shared 1990-2005 shape, so they sit on an NB, but the Miata.net FAQ says most (perhaps all) have the old-style front latches and an NA-style defroster plug. On a 1999 to early-2003 NB the latches match; on a car built from November 2002 on, you would need late-style latches. A heated rear window would need the NB-style defroster pigtail. Owner feedback on several aftermarket tops is mixed, so a used factory top is usually recommended. Forum-level and summary sources only.
