While working on my dash on the 67 convertible, I found the heater 
  switch to be broken, so I did some web surfing and I stumbled aross this on 
  another mopar board. I have provided a link to a photobucket album with some 
  pictures he sent me. he repairs those pesky plastic nipples (actually make new 
  ones) Mike Becker 
  Here is the excerpt of the email he sent me.
  Subject: Fw: Re: vacuum switch repair
Mike,
  Do you 
  have any pictures of the rear switch you are talking about?
I think the 
  main switch is just like the ones in then a,b,and c bodys. Can
you send me 
  a link to your forum?.  I don,t have a web site.  I 
  just
advertise on all the mopar forums.  At the bottom of this 
  e-mail  there is a
link to my picture album that has pictures of the 
  various switches that I
build and 
  repair.
Thanks,
 Anthony

Mike,
  Below is a canned letter that I send to 
  everyone showing my service and
what the charges are. So far I have been 
  able to get the switches back in the
mail the day after I receive 
  them.  If your car is a62-65 air car be sure to
check your temp 
  selector switch located on the right side o the plenum
(picture #3). The 
  average cost to rebuild the switch is usually about 45.00
plus 5.00 for 
  shipping.  It just depends on how much work needs to be done.
If your 
  buttons are a little hard to bush it usually needs at least 2 of the
wafer 
  boards.  
If your really lucky you can get off with just the vacuum 
  port repair.
  I would need you to send me your switch or 
  switches.  There is some machine
work that I have to do no the switch. 
  I can fix several problems that happen
to most of these switches.  The 
  cost just depends on what is broken on your
switch. I can fix AC/Heat or 
  Heat only switches.  I have rebuilt switches for
people all over the 
  United States.  Rick Eburg did an article on my repairs
in the 
  March
2006 edition of Mopar Action. 
   Picture #1 is a before 
  and after shot of the vacuum control switch. It
will work on any push 
  button mopar switch from 1959 to 1988.  Picture #2 is a
before and 
  after shot of the push button repair.  Picture #3 is a before 
  and
after shot of the Temperature selector switch for 62-65 b body 
  air
conditioned cars.  Picture #4 is a before and after shot of the 
  max cool
vacuum switch that piggy backs on the fan switch on the 62-65 B 
  body air
cars.  
Picture #5 is a before and after shot of the 
  sliding wafer boards that go
inside the switch.  
  I have 
  been using a repaired switch in my car for over two years now and it
works 
  great.  The port and button repair is made out of black or white 
  delrin
material.  It is super tough.  The other two switches are 
  made of alum.  They
will all outlast the cars they are going in.  
  The wafer boards are made out
of a super tough plastic shim stock.  
  The vacuum port repair is 35.00, button
repair 5.00 each,and wafer boards 
  are 5.00 each. The temp selector switch is
35.00 as is the piggy back max 
  cool switch. Just send a money order for the
services that you think you 
  need.  I won't know if you have any bad boards in
the switch until I 
  open it up.  If there are bad boards you can send payment
for them 
  when you get your switch back. I can be reached  at
aepowell3@xxxxxxxxxxx or (903)-893-5674. I thank 
  you very much for this
chance to show my product.
