I replaced my inoperative hydraulic stoplight switch with a standard 
plunger type today.  Probably the easiest change I ever made.

If anyone is interested...Standard part # SLS66, a piece of flat stock 
about 1 1/4" wide, some wire and connectors.  I used some flat stock I had 
laying around that had holes in it already it isn't necessary but it made 
it even easier.  I cut it on an angle so it would orient the switch dead 
center on the brake pedal.  The existing hole in the factory pedal support 
is a little to the left of the pedal.  The 3/8 holes in the stock are 
perfect for bolting it to the pedal support using a 5/16 bolt.  I used a 
nylon self locking nut and put the bolt head on the pedal side.  I didn't 
want the bolt interfering with the pedal.

The plunger hole needs to be 1/2" so you'll have to drill.  Once the 
bracket and plunger are bolted up adjust the plunger so the pedal pushes 
the button in when your foot is off.  It should be pushed in all the way 
but the pedal should also be at the end of its natural travel.  Easiest way 
to do it is to set everything up and turn the nuts that come with the 
switch so the switch rests fully against the pedal with the button all the 
way in.

If your factory harness is intact at the stoplight switch you can buy male 
terminal ends that will plug onto the female terminals that were attached 
to your factory switch.  If the ends are loosed or cracked at the 
insulation I would just splice or butt connect the wires that will extend 
into the interior.  I wrapped mine pretty with electrical tape and put them 
through the firewall where the speedo cable comes out.  Then it's simply a 
matter of cutting them to length and putting female spade connectors on the 
ends.  There is no wrong way to put them on they can go on either terminal 
at the switch.  Check the operation making sure the lights are off when 
your foot is off the pedal and that they come on at the slightest touch.

I've posted pictures of the installation in the "Photos" section on the 
group site along with some pictures of the car itself.  I need to get the 
bumpers on and some trim installed but the car is getting close to 
completion.  I won't use the word "finished", I know better!
