Wow, that's very interesting, if true. Don't know about the status on my
pal's old '65 (in the incident described below), but my car was missing
all four and its hood was creased, so there's a corroboratory example.
I've since installed two bumpers near the trailing edge. From your
description the leading edge ones are likely to be the most important.
Something to think about...

Runs great,
looks particularly bad since some SUV clown backed into it.
If you're near Mountain View, CA,
it's the red one with the silver bootlid.
