I have turned up a couple of original style jacks, including latter style 116 series jacks that are supposed to have the teeth and gears made from steel instead of brass that the failure prone jacks have.
At $100 to $150 it’s not a cheap option though.
An interesting find was the $20 scissor jack from Supercheap Auto that actually has a rotating top fitting with a slot in it that can be widened ever so slightly, maybe 1mm each side, to fit around the existing jacking point. I personally think that’s a better way to go.
