[V8] Alignment specs

Tue May 22 15:50:02 EDT 2007

Ah... Good to know.  Fortunately, I've only ever jacked the V8 up at the
jackpoints, and always use a block of wood between the jack and the car.
And jackstands under the control arm mount...

I've always been tentative about lifting a car under the rear diff (or
the bellhousing on FWD cars), but I guess I've just never analyzed why I
felt that way.
