My personal opinion is that its safe. Obviously the car wont handle as well, but if youre not pushing it hard, its doubtful a person could tell, as you stated.
Id say it probably does put an extra strain on things though, but for no longer than youre planning on driving it that way I doubt it would hurt much. But I would get it fixed as soon as youre able.
Im not sure if your state has safety inspections or not, and if so how stringent they are, but it is something that could cause you to fail inspection. If the inspector knew your car was supposed to have one, some vehicles dont even have one.
I also noticed either my link disappeared, or I didnt post it right in my first post. I linked you to the whole GMPP handling kit, but youre probably not interested in souping up the old gal
