I bought some used lower 1/2 soft doors and I am not sure if they will fit Broncos fiberglass inserts or not. I bought the doors used but they were unsure what they fit and I took a chance, but they appear to be the same shape and size of what I see on other early broncos. I don't have inserts to check the dimensions, but I was seeing if someone could help me by measuring the opening on your inserts to see if my doors will fit. Thanks for your help
