thats what i was gonna suggest before i even saw your post! while it might seem like a big front should go with a big back, the big back bumpers just dont flow with a single line or shape on the car. on the other hand, the big front bumper really fills an otherwise pinched looking front end. (it just needs to be tucked to flow properly)
What all did you do to the front bumper to tuck it. My wife wants this done on her 77 comet. Any more pics of the front bumper tuck.
