'8x Coupe rear light clusters

[ejfluhr@wc101.residence]

Has anyone had to replace the rear brake light cluster on their 80's
Coupe/GT?  Both sides of mine are starting to give me lots of trouble
with shorts, broken connections, etc.  I've gotten by with sanding the
contacts, but now they are having other problems.  I think it would just
be easier to replace them.  Anyone know of prices and availability?
I think this might be a dealer-only part :-(, but I can always hope.

Also, ideas on how much the switches for the back-up lights and the
5th gear upshift lockout cost (the ones on the manual tranny)?  Both 
of mine appear to be broken.  Are they the same part number?
How hard are they to replace?  If memory serves me correct, they are
on the top (??) of the back of the tranny.
BTW, this is on an '85 GT.

Thanks,
Eric

P.S. I saw one of the new Audi commercials the other day.  Had an Audi
Quattro of some sort (was on a restaurant TV, didn't catch which car)
going up a hill with the tires on one side on a slippery mat.  Had a Benz
and BMW (?) trying vainly to get up the hill, and I caught the announcer
mention traction control.   Seemed like a cool commercial.
