To make life easier, I'd get a low-profile jack. I've used normal sized jacks, and low profile jacks. If you're jacking up from the front or the back (diff), you will need a low jack.
I have a "big red" racing jack, my brother has a harbor freight racing jack. Both BARELY squeeze under the front bumpers of ours (our cars are 1" lower).

If you're wanting to jack from the side, you will need a side lift jack pad:
