Question about jack stands

OK back to serious again. In the Autozone link that waterbluff posted, they illustrated putting the jack stands under the frame rails, not the pinch welds for the front. I hadn’t seen that before and would feel more comfortable with that. Pinch welds for the rear and frame rails for the front. Any comments on that.

Also as far as the rack goes, that is a very difficult thing to change out or work on due to the need to have the front end up off the ground and limited space to work. I had considered it years ago with my Park Ave having the ole morning sickness, but after looking at the procedure, decided that was one job a shop should do on a hoist. I still feel that way. Maybe the mechanics here don’t see it as any big thing but it wasn’t something I would tackle.

Also even with jack stands under the frame rail, I would still want a floor jack in front or a couple more jack stands on the front end just in case, and of could a cell in my pocket.
