With the flat portion of the roof, it looks a little like a sketch of the 2+2.

I had thought about making some slotted rubber pucks for the rocker panel seams but at home I just used the diff or the front cross member and the sub frames were dented anyway.

I wonder how well a Z would lift using the four points shown in the Owners Manual. Is that not the ugliest drawing of a Z ever? 1973 Owner Manual. Looks like the summer intern did it.

Yeah this would be awesome. You can probably start with 3D printing prototypes. I know BMW has something similar with an adapter that can be mounted in a standard hydraulic jack. I believe it's called a "Jack Pad" or similar...

I've been using slotted hockey pucks as lift pads for several years. They work quite well. Just make sure that the slot is wide enough to keep the puck from wedging itself onto the pinch weld strip and deep enough so that the load is taken by the rocker and floor panel metal on either side of the pinch strip (rather than by the pinch strip itself).

I think I'll just stick to the rear differential or the front crossmember pad, never had a problem with these points.

I ran into this at a local tire shop: Several years ago I had them install tires I purchased elsewhere and they were happy to do it. I told them I wanted them to use a floor jack and lift by the front crossmember for the front tires and by the differential for the rears. They did exactly that. A few years later I went back and asked them to do the same thing and they would not - telling me that new corporate guidelines prohibited using a floor jack - they could only use the installed lifts.

You can do that at home and possibly if you find a small shop that will agree to that method, but most of the large chain tire shops will probably not. Couple that with a crop of installers only used to dealing with modern cars...

The damage to the above fender was done by failing to use an extender under the pad at the end of the lift arm. It's the lift arm that did the damage because it wasn't properly spaced to avoid contact.

The last time I got tires I took the wheels off the car and went to the tire store. They did mount and balance (no outside weights), I took them home and put them back on the car. No issues.

That’s exactly what everyone needs to do.
