After studying 7425 for a bit, I noted that the official factory line is to
just loosen the aft engine-block bolt on the FD upper bracket, and remove
the long bolt and the forward engine block bolt. Then, the bracket can be
tilted up to provide clearance. That still means removing my ultimate
nemesis, the power-steering bracket, which also uses that forward bolt. I
might be able to get a wrench on it to just loosen it.
It took two wrenches of different designs--one with a lateral bend and one
with an offset--to get the block-side bolt on the FD, but I was expecting
that. Those GM engineers worked out all the details of this arrangement,
but maintainability, as usual, wasn't high in their list of requirements to
fulfill.
I'm using a scissors-style transmission jack for the lowering of the FD,
and I really do hope that works. My wife's uncle had bought it from HF, so
the first thing I had to do was fix it. He's telling everyone he's ahead on
the transaction because he got his jack fixed.
