Its a fender off an 88 Mustang and is an original Ford part.You are right about repro fenders, i tried one off a diff parts car that was a made in taiwan fender(it was only one i had at the time
) and it didnt fit properly.It stuck up higher than the nose section where fender/nose and hood meet.It took me maybe 1-2 hours to remove old fender and put new one on then line it up properly, it fit perfect all body lines match up.You can reach in behind headlights thru engine compartment/front area and remove the 4 or 5, 11mm nuts with a small ratchet/socket. 3, 8mm across the top in engine comp, 1 in door jam area behind driver door and 1, 8mm at the bottom between wheel well and drivers door.The 3 screws holding the inner fender can be accessed with the wheel removed.Just carefully wriggle it off the front studs and lift it out and backwards to rear of car more or less.
As long as its American its all good
itd be a lonely drive with no Camaro's,Challengers ,Corvettes etc for competition.
Ive had pretty much my entire car apart now, completely gutted the interior to mop up the antifreeze( previous owner shinanigans again), entire dash was out to replace heater core,i pulled engine and tranny one friday night just to wash the engine down of all the grime ( and repaint) and to fit new engine mounts for
BBK headers and complete exhust.Its all back together no rattles squeaks, runs excelent-much to my own astonishment
