Jack points?

Hey. I just bought a floor jack, and I'm curious what parts on the car I can use to jack it up (aside from the factory scissor jack locations... Like, if I want to jack up the back end of the car, can I put the jack somewhere at the back in the middle or something? Same for front end...

Theres a bump on the front crossmember you can use, just look under the front and you should be able to tell. For the rear, i use the rear tow hook, dunno if theres any place better in the rear.

Whenever I jack up my car I aways use the spot on the front (is a metal bump which my jack fits right into), and for the back I use the rear tow hook.

yup me to ............. is it a big jack or a lil one?
