Hello Guys I just bought a billet grill for my 1997 expedition. I took it to a pro but he told me that he had never put a billet grill like mine in. He told me mine was to long but I have read on this topic and some grills are insert and some are where you have to cut the whole hosing of the old grill out and put the billet one in. Here my question are they 2 different types of cuts for the billet grill in order for it to work?
