The screws are accessible through the magnesium plate from the top.
With the IC removed I was able to scrape off the glue and loosen the
screws with the use of an inspection mirror and a small flat blade screw

Charlie, it sounds as if you took out the steering column and steering
column support.  The Bentley shows the wrong diagram for this.  On my
car, the steering column slides into the support via a dove tail tongue
and grove.  I had to "knock" the steering column down with a plastic
mallet.  Zero screws to remove except the ones at the knuckle near the
fire wall.

You do need to drill one 3mm hole per the Bentley to remove the lock
cylinder.  Must be a VW/Audi thing.  Did same thing on a Corrado once.
You still need to remove the steering column.

Same here, A security Torx????...T35 $3.00 at Mcguckins, Bummer to have
to cut the tape with an x-acto knife to remove the security torx stop
work to buy a tool.  It does go out and back on in one piece just fine
as Charlie reported.  Torx screw can be removed in the comfort of your
living room

I thought about adding a "Push to start" button and do away with the

And all that spare change!
