1973 Dodge Dart 4-Door Custom Sedan Rebuild
Passably decent and very inexpensive '73-'74 Dart turn signal lenses can be had new out of Mexico, part № 23C made by
these people. Probably difficult to deal with them directly, but
this guy has a bring-yer-own-silver-paint pair for cheap money. Don't get too excited with that first link; the Mexican-repro tail lenses for '71-'73 Dart are not good enough to mess with.
Me, if I'd kept my '73 I'd've replaced the whole dim factory park/turn lens-reflector-bulb assemblies with a pair of good quality(!) LED units. If I were to insist on damn-near-original appearance it'd be
these Signal-Stat 6051A clear-lens/amber light units. If I wanted maximum performance/clearest visibility of the turn signals and ability to use them as daytime running lights (see
here; important in Canadian traffic where virtually all cars have them and cars without are at elevated risk of being hit) it'd be
these American-made Peterson 821A-10s, which are quite a lot brighter. Either lamp is virtually the exact right size and shape; only a tiny bit of a shave off the left and right ends of the grille openings will be necessary for them to fit right in, and their lifespan is super-long; enough that you could just glue 'em in place without fear. You'd need a new flasher to operate the LEDs correctly; that's
this one (2-prong like original; connect its ground wire conveniently). You'd also need two PL3 pigtails to connect the new lights—that's
this one.
While you're at it, put
these in the brake lights (Canadian link
here) and
these (Canadian link
here) in the back-up lights, after cleaning the rear lamps' reflector bowls and shooting 'em with "chrome" spray paint from the hardware store.
Speaking of chrome: yep, $1,400/bumper is way too expensive. How 'bout
this instead? The supplier is
here.
