why can't you get at 76-77 aspen grill and the filler dodge panel above and put it on a 78-79? or a 73-76 duster grill with the 76-77 dodge logo filler panel those grilles are so easy to find.
A body grills wont fit the J body they are designed to fit the headlight bezel's the early j bodies would work, but I like the cleaner look of the 79;s directionals.
what I dont like is that they are plastic,so if have to pay for a grill,and I can get aa billet grill that fits, thats a better use of my money, ]
right now though, it has a grill that fits, so there is no reason to change it
