I put all this info on a page in the technical section of my website, but my host server won't let me upload it at the moment. It will be online soon.
Cheers!

Allright Garth! Thanks for the consolidation
of the data. This e-mail with your and Chris Defani's pics, that were sent
to me separately, belong on the POCA website in the tech section. Very
helpful,
Thanks Guys

Hi
John,
Since everyone's been so busy pontificating the merits of
the pressure actuated brake switch rather than answering your question,
I thought I'd give it a go...
Stock
Replacement
-----------------
I have a catalog from Graham Pantera
(Graham tool company) selling the stock part for $24.95 (part#
01321A)
VW Brake Light Switch from NAPA #SL147 -- Not
Recommended (read
below)
----------------------------------------------------------------------

It's
a perfect fit and has the right connectors
according to Steve Hawkins:

HOWEVER...
Others have found that it's NOT an exact fit...
Ian Hannington found
that
#yiv174872154 #yiv363536980 #yiv65676783 #yiv65676783 P.MsoNormal {
FONT-SIZE:10pt;MARGIN:0in 0in 0pt;FONT-FAMILY:Arial;}
#yiv174872154 #yiv363536980 #yiv65676783 LI.MsoNormal {
FONT-SIZE:10pt;MARGIN:0in 0in 0pt;FONT-FAMILY:Arial;}
#yiv174872154 #yiv363536980 #yiv65676783 DIV.MsoNormal {
FONT-SIZE:10pt;MARGIN:0in 0in 0pt;FONT-FAMILY:Arial;}
#yiv174872154 UNKNOWN {
MARGIN:1in;}
#yiv174872154 #yiv363536980 #yiv65676783 DIV.Section1 {
}
the stock switch has a 1/4'' pipe thread while part #SL147 has an 1/8''
tube thread.

Jack
DeRyke confirms and points out that the connectors are different
too:

GM Brake Light Switch
---------------------
Jack DeRyke
reports that
adapting an '82-up GM style mechanical
brake light switch to the Pantera brake pedal is not difficult, saves
considerable money and forever fixes the brake switch
problems.

GM
Brake Light Switch
---------------------
Forest Goodhart used a
switch from any mid 80's Chevy without cruise control and found it to be
very quick and easy.

1.
He used a piece of flat bar about 1"x3/16"x2"-3" long.
2. Drilled a
hole near one end that the switch would slip through and a hole near the
other end that fits the shaft size of the stop that the brake pedal hits
under the dash.
3. Unscrewed the stop, inserted the bar, replaced
the stop and adjusted the switch so that the pedal just pushes it enough
to turn off when the brake pedal is released.
4. Then intercepted the
wires going to the original switch and connected them to the new switch.
He reports that it was easier than it sounds.
Generic
Plunger Switch from a CNC Milling
Machine
----------------------------------------------------------------------------
Chris
Difani used a limit switch for a CNC milling machine. It's
stainless steel, and is designed for severe usage within a machine tool
environment. It's got a spring loaded plunger set in
a stainless steel case and is designed to work in more than one plane.
Check with Chris to see where he ordered it (he gave me one as a
matter of fact because he had extras).

I added Chris' info and pictures to a page on my website, but for some
reason I cannot publish it at the moment. I'll forward the pics to you
directly.
