^ yep. i did mine a few months ago. by far, it was the most pain in the ass job i've done on the supra. i'd rather pull 6 motors in 6 days than do that crap again.
i used a sawzall, and a torch when i finally got fed up with it. (short bursts with the torch). i had new nylon bushings, so i didn't give a damn about the old ones.
also, do yourself a favor while they're out. clean up the surrounding areas around the tabs that the eccentric lobes rub against with a wire wheel and some brake cleaner. bend the tabs perpendicular to the chassis. (how they're supposed to be, and many of them will be bent). then run a bead of weld behind each one on the outside to prevent it from bending ever again.
when i pull my rear subframe for the solid spacer install, i'll be doing the same back there while i have it all out. the rear of my car is a tiny bit out, and that's the best it'll be until i can fix those tabs.
my alignment guy loved me for that.
use LOTS of antiseize (i call it seldom-seize, heh) on re-installation.
good luck!
