1968 Dodge Dart GT Front Grill -> 1967 Dodge Dart GT

the 68 tailight buckets will fit the 67 body if you work the area into a 68, otherwise no.

what do you mean with "if you work the area into a 68" ? is there bodywork needed?

on the grill it should work given that its not a 69 (69 they moved the headlights all over to prep for the 70 model year grills)

the grill is so then no problem.
