I've been trying to locate a front end assy for my 77 442 for several years. I can't even find grills anywhere-(that anyone will let go of anyway).
I did put a 77 nose on her for a couple of years but it seemed so ---wrong.
I just had to take it off. Let me know if you find a good supplier for parts for that car, it seems to be an odd ball. A lot of parts are interchangeable but it seems that most the parts I need are specific to that car only and are hard to find.
