Why does it need to be slotted? The bottom of the slot is flat. Flat is flat.
To me the only way a slot matters is if it's EXACTLY the right depth to weight the bottom of the pinch weld and simultaneously the body at the top of the flange
So this is the factory OEM scissor jack for the Lexus and Toyota we have. As you can see the slot is deep instead of just an indent for alignment for older vehicles with THICK plate (like 3-5mm of steel) instead of think sheet metal (like 1-2mm). The load is on the top flat surface and against the bottom of the "rail" instead of the vertical pinch together thin sheet metal.
Hence I'm trying to see what do people use and as mentioned here: sawed 2x4, hockey puck, slotted plastic or rubber, TT shape metal alloy, don't bother and just let the pinch weld deal with the bending etc. I would rather spend a few bucks than bending it, and in the worst case replace it once very few years.
About how to spread the load around, seems like so far I haven't seen any ultra long adapter that expand more than 2-3 inches. I guess the "best" would be some 6" long TT shape metal adapter but having it balanced on the jack / jack stand would be a concern.
The other concern is how do you keep it stable on a jack stand that is U / C / V shape on top with a flat metal or plastic puck? It has to stay balance while you lower the car on the jack stand from a hydraulic jack and not tip over.
