NA/NB Miata Factory Front Fenders: Generation, Side, Liners and Splash-Shield Identification
US/LHD 1990-1997 NA and 1999-2005 NB Mazda MX-5 Miata factory bolt-on front-fender applications only, separated by NA versus NB generation and left/driver versus right/passenger side. Resolve the recipient VIN, model year, build date, side, installed panel shape, paint code and 2004-2005 standard versus Mazdaspeed/turbo splash-shield branch before ordering. Exclude the US 1998 gap year, 2006-up NC/ND, non-US/RHD catalog assumptions, rear quarter panels, fixed apron or rail structure, widebody/overfender kits, unsupported NA/NB conversions and cars with unmeasured hinge-pillar, rocker, upper-rail or bumper-support collision damage. The checked US fender diagrams do not establish a fender-mounted side-marker opening; keep bumper/lighting marker work in the existing front-fascia guide.

Start with the recipient VIN, US model year/build, NA versus NB generation, left/driver or right/passenger side, standard versus Mazdaspeed/turbo where applicable, paint code and complete photographs of the installed upper, lower, rear, hood, headlamp and bumper edges. Match the shell number where available, then inventory the liner, separate splash shield, seal tape, clips, bolts and every adjacent bracket individually. A bare fender normally omits the liner, splash shield, seal tape, clips/bolts, bumper retainers, lamps, badges, mud flaps and hardware unless the listing itemizes them. MIA-0046 owns NA/NB front-bumper covers, reinforcements, retainers and side-marker lamps; this guide does not relocate the checked bumper-mounted marker identity into the fender. Inspect used panels at the wheel lip, lower rear edge, upper flange and bumper/headlamp corners for rust, dents, stretched metal, filler, repaint, welds, torn holes, distorted flanges and freight damage. Require donor VIN/generation/side, underside and edge photographs, paint condition, packaging and return terms. Measure and repair damaged apron, rail, hinge pillar, rocker or bumper structure with current VIN-specific Mazda procedures and qualified collision/body work before panel-gap alignment; verify hood, door, headlamp and bumper gaps, liner retention and tire clearance before driving.

The checked 1999-2004 collision guide lists separate splash shields: 1999-2000 right NC10-56-132E and left NC10-56-142D2001-2003 right N067-56-132 and left N067-56-1422004 turbo R/L N115-56-13ZAand 2004 non-turbo R/L N067-56-142, with common shield bolt 9CF6-00-520B. These are panel and wheelhouse verification identities, not one complete fender assembly.Supersession
The checked current Mazda seller catalog explicitly states NB right fender NCY0-52-110E -> NCY0-52-110F and NB left fender NCY0-52-210E -> NCY0-52-210F. The checked exact liner pages state right NC10-56-131C, NC10-56-131D and NC10-56-131E -> NC10-56-131F, and left NC10-56-141A, NC10-56-141C, NC10-56-141D and NC10-56-141E -> NC10-56-141F. NA and NB fenders and liners remain parallel generation families, not one interchange chain. The checked collision guide's 1999-2000, 2001-2003 and 2004 turbo/non-turbo splash-shield identities remain explicit application branches; no unsupported supersession is invented among them. Shared clips or similar seller photos do not establish NA/NB, left/right, standard/turbo or fender-to-splash-shield interchange.
Fitment
Start with the recipient VIN, US model year/build, NA versus NB generation, left/driver or right/passenger side, standard versus Mazdaspeed/turbo where applicable, paint code and complete photographs of the installed upper, lower, rear, hood, headlamp and bumper edges. Match the shell number where available, then inventory the liner, separate splash shield, seal tape, clips, bolts and every adjacent bracket individually. A bare fender normally omits the liner, splash shield, seal tape, clips/bolts, bumper retainers, lamps, badges, mud flaps and hardware unless the listing itemizes them. MIA-0046 owns NA/NB front-bumper covers, reinforcements, retainers and side-marker lamps; this guide does not relocate the checked bumper-mounted marker identity into the fender. Inspect used panels at the wheel lip, lower rear edge, upper flange and bumper/headlamp corners for rust, dents, stretched metal, filler, repaint, welds, torn holes, distorted flanges and freight damage. Require donor VIN/generation/side, underside and edge photographs, paint condition, packaging and return terms. Measure and repair damaged apron, rail, hinge pillar, rocker or bumper structure with current VIN-specific Mazda procedures and qualified collision/body work before panel-gap alignment; verify hood, door, headlamp and bumper gaps, liner retention and tire clearance before driving.
Aftermarket options
Checked aftermarket paths expose reproduction stamped-steel NA/NB fenders, painted or primed panels and widebody/overfender products. Keep factory-service identity separate from aftermarket application claims. Require written NA or NB generation and side fitment, material/gauge, every hood/headlamp/bumper/door/rocker and liner mounting point, corrosion coating, finish preparation, included hardware, freight-damage procedure and return/warranty terms. Moss and Mike's show reproduction NA choices, but a seller's broad 1990-2005 selector is not proof that one physical panel spans both generations. Avoid universal flares, cosmetic overlays presented as structural repair, cut or rewelded flanges, marker-cut imported panels and any listing that hides the actual photographed part, prior repair or required liner/splash-shield pieces.
Before you buy
US/LHD NA 1990-1997 and NB 1999-2005 only; match VIN/generation, side, installed panel and 2004-2005 standard versus Mazdaspeed wheelhouse pieces. NA and NB shells/liners are separate families. A bare fender omits liners, splash shields, seal tape, clips, brackets, lamps and hardware unless itemized. Checked US diagrams do not establish a fender-mounted marker opening; MIA-0046 retains bumper/marker scope. Inspect rust, filler, welds and flanges, confirm freight/returns and use qualified structural measurement/alignment after a collision. Seller states are dated snapshots.
