RARE 73 Dart Sport 4 speed?

what's its v.i.n. ?

That is a '75 grille ; '76 had ambre-coloured lenses .

O.D. trans was a late '75 intro .

8.75" diff was last used in 1972 in "A" Bodies ; 1974 in "B" , "C" and "E" . An 8.25" was the best rear for '73 & later .

Maybe you've got a '73 340 or '74 360 there , with the later grill (?)

Post v.i.n. and fender tag if possible .
