THAT'S WHAT I WAS LOOKING FOR, THANKS! I LIKE WHEN EVERYTHING IS FUNCTIONAL AND CORRECT. THE CAR IS A TIME CAPSULE!!

like Lloyd was saying on that rear A/C bracket, Sonic made a run of reproductions and they did still have a number of them in stock about 3 months ago when I bought one. It's a very high quality piece, I think they were $175 or so when I got mine.

Fan & pulley should be silver zinc/cad plated

Brent, great posts and pics. Congrat's on the find and thanks for posting up these pics.

Where is the shaker solenoid switch on your auto and 4spd? Are they both wired the same way?

Shaker switch on 72 T/A's was no longer on the carb.

The TH400 kickdown switch above gas pedal was used to activate shaker door,even on stick cars.

Brent, That is a spectacular find! Thanks for posting and many thanks for the invaluable pictures.

here are some pictures of the 4spd and auto kickdown switch

Thank you for those detailed pics on the shaker switch! You know I'd ask... what is that diode that can is wrapping over the switch on both cars? I'm familiar with the kickdown switch itself, but haven't seen the diode before.

Also, for the automatic car, does this mean the shaker door opens when the TH400 kicks down? Both happen at the same time?

[ccie3611]

not sure why the diode is there, it was on both cars so i'm sure its from the factory. not sure about the th400 kick down.

[ccie3611]

here's an interesting tid bit, notice how the hood stripe decal bends half way into the shaker opening lip - that would be very difficult to do.

That diode seems to be only on the '72 models. I think it's there because the '72 switch performs two tasks. It downshifts the transmission and it operates the hoodscoop door, and they do operate at the same time.

That's what I was thinking as well, Jim.

I just checked my '72 SM, and the diode is not documented in the F-body wiring diagram though.

A diode is like an electrical version of a check valve. Energy only flows one way through a diode. I wonder why they needed it?

Edit: I looked at the picture and my guess is that is a resistor, not a diode. Those are color bands if I'm not mistaken.

i was thinking the same thing - its a resistor

I believe the 1972 auto-equipped cars got the resistor'ed switch and the 4-speed cars did not. Since it was used to trigger two seperate electrical devices on an auto car, I think it was set up as a heavier duty model so it wouldnt burn out, working the 2 circuits at once.

This must be one of those IQ tests because I cannot get my brain to read what I'm looking at in the photo. Is it 2 people kissing...or an old lady and a young lady in the same image???

:-)

Can you uplink a wider angle shot?

I had to study that pic for a while myself, Steve. It's shot across the top of the hood, looking towards the passenger side. The blue background is what's so confusing - Brent's M22 T/A is parked next to this one.

Rick - I thought that I remembered you were gonna buy one of those brackets from Barry.

Have you any idea yet if it's gonna fit properly?

LOL!

I can see it! I can see it!!!

(Thanks for humoring me)
