stuck high-beam, pilot-bearing etc

Just an update and a quick question.  Got buried in 115 msgs awaiting me after
a week's vacation.  I finally got the Boge TG struts done on my '87 5kcst, new
OEM Leistritz muffler and new BFG Comp T/A 215/60 tires.  The car handles 
better than new with 122k.  Much stiffer and better-handling.  

On to the questions:

I have the classic broken headlight switch stuck on high-beam, before I tear 
into the steering column, for those of you who've BTDT, can this be fixed 
short of a replacement?  The car failed inspection for this and I'd prefer not
spending $150 for a used one so I figured since it's already broken, I can't 
do any worse damage...

In my ongoing self-taught automotive education, I'm helping a friend do a 
clutch job on his '87 RX-7.  We had the trans out in a couple of hours, it's 
really light!  After removing the pressure plate and clutch disc, we found 
that the pilot bearing had completely disintegrated!! and only the shaft 
remained.  We tried using a generic KD Tools pilot bearing puller but it's 
really stuck tight.  We then used a small propane torch to heat the 
surrounding area (flywheel nut enclosing the bearing) but no go.  
Any ideas/tricks, anyone??  If Mazda doesn't have a special puller tool, we're
going to resort to brute force and chisel the bearing shaft to pieces.

Any advice appreciated!

P.S. June issue of EC has a cool tech article on Audi 5-valvers as in the A4.
Also featured is a 428hp S2 RSR quattro coupe.  0-60 in 3.9...
