I have Fox factory steel "shorties" and a 302 in my 1970 convertible. I guess I should change my signature one of these days. I've been waiting until I actually get the thing running again.
The driver's side flange had to be notched to clear my steering box. I have manual steering. So it did fit in my car, but not without mods. I'm also a little worried about how close the manifold is to the box. Hopefully it won't cause me problems.
Edit: I foolishly threw away a set of the shorties when I parted out the '85 GT last summer. It cost me $20 for another set.
