Proof? I followed this website EXACTLY how this guy did it. Sure I have an 86 and he did it on a 91, but it slid right into place. I didn't have to lift a single hammer or prybar. The Ford guys are obviously lazy and would rather have you beat the tower than simply elongate the holes. I took my time and it popped right in, so maybe I have some fluke car, but I did no bashing.

Look at the "under the hood" part and you'll see what I mean.
