hi,
it's 3 bolts that hold the aluminum bracket to the rear of the engine.
there's no need to unbolt it.  You just remove the 4 rubber mounts from it.
Be careful about those 3 bolts, several times I've seen one of the upper
ones broken off in the block.
Not fun to repair.  If all 3 bolts are intact and tight, I just leave  them
alone.
Sometimes people think it's the rear rubber mounts that are worn, when what
it really is ................... some of those are shot, plus one of the
upper aluminum bracket mounting brackets is broken, or might have loosened
up.

But yes, lower the back of the engine, support it, remove the large cross
bar from the bottoms of the four rubber mounts, and see if there's enough
room to sneak the mounts out.
