Thanks for all the help, y'all. Breaker bar did the trick. So, now, the shimmy is vastly reduced but still there under braking from about 60-65 -ish. Haven't had a chance to Interstate it, will try tomorrow and see what happens.

Is it worth the trouble with Mintex pads and cheapie disks to set the pads aggressively? I'm not a very aggressive driver, so don't know if it'll be worth the effort.

Headlights next, more to follow.
