in lieu of that type of cost, how does one use a midsize floor jack and jackstands to get an Amphi up so as to creeper around underneath (paint bottom, etc) ?
What jackpoints and jackstand-points are advised?
If you use a 4x4 to span from rocker panel to rocker panel, behind the front wheels or before the rear wheels, you can put the jack anywhere along its length. The 4x4 will bridge the space between the frame rails. (at least I've had no issues using this method many times)
