Alternately,

• you can just drill a couple screws into your workbench to line up with these holes here:

• Then use some heat to loosen up the nut on the back plate and break it free with a long wrench (or use a spare set of handlebars for a lever).

• Once you break the nut free, use some big channel lock pliers to break free the back plate.

• also, I noticed that these screws here:

Had been locked in place with little dabs of weld. I had to clear out the slots with a flathead screwdriver and some firm but gentle hammer taps.

• I like this way better because there is much less chance of warping the variator with the vise.
