OT How to straighten a bumper?

A friend, a different one this time, was hit from behind Wednesday
night, while stopped at a stop sign. The other driver sped off, and
he found the bumper on his Nissan 1/2 or 3/4 ton pickup was pushed
maybe a foot out of place.

Today we attached a come-along to a big light pole and the other end
to the bumper just inside the bumper bracket, and then on the other
side, and moved the bumper about half-way back to where it was. The
cable didn't seem to come close to snapping, but we were careful
anyhow. (At least he was. He sat in the rruck and let me crank. )

He had to put the truck in gear, in park if it had it, and put his
foot on the brake to keep the car from moving while I cranked.

Now the question I'm asking is, How to get it the other half of the
way? Now, in order to finish, the bumper doesn't need to be pulled
back so much as up.

I thought of finding a bridge with a diagonal girder, or maybe using
the big Gateway Arch in St. Louis, but that will lift the whole truck.

How do we hold the truck down while we do this? It has a cap over the
bed.

Actually, we probably don't need a bridge girder, just a floor jack or
two, and we have that, but we still need to hold down the truck.


BTW, he's also looking for replacement bumper brackets but not doing
too well on that. I don't know what year the truck is. And if we
could just finish bending it, it would be a lot less time-consuming.
The first half only took about 20 minutes, once we got started.
