Diagnose a broken nylon mast cable versus dead motor/power/ground before buying. NB B05A-66-A30 is a mast-only path. NA N007-66-930A is a complete assembly reference. The checked retrofit begins at 1992, so 1990-1991 cars are excluded from that live path.
OEM numbers
NB genuine electric mast B05A-66-A30 for 1999-2005. NA used power antenna assembly N007-66-930A for 1990-1997. Checked RetroSound replacement power-antenna kit covers 1992-2005 as an aftermarket retrofitit is not an OEM manual-antenna conversion.Supersession
Separate repair paths: NB mast-only B05A-66-A30; NA complete used assembly N007-66-930A; aftermarket 1992-2005 powered retrofit. No NA/NB interchange or manual-antenna OEM chain is claimed.
Fitment
Diagnose a broken nylon mast cable versus dead motor/power/ground before buying. NB B05A-66-A30 is a mast-only path. NA N007-66-930A is a complete assembly reference. The checked retrofit begins at 1992, so 1990-1991 cars are excluded from that live path.
Aftermarket options
Checked genuine NB replacement mast, used OEM NA complete assembly and a 1992-2005 RetroSound powered retrofit. Manual-antenna conversion was removed from the public claim because a complete verified OEM base/mast path was not live-checked.
Before you buy
NB mast-only repair is not an NA assembly. Confirm the motor runs before ordering a mast. The checked retrofit covers 1992-2005, not 1990-1991. Manual conversion remains search-only because its complete OEM parts path was not verified.
