There's been some off-board converations on this thread concerning the 'extra' hole in the RH lower dash panel bracket. The hole is there to mount the 'Jesus' duct on A/C equiped cars. What's a Jesus duct you ask?
Well if you flip to the C60 option in your AIM books, you'll find there's a duct that connects the center Harrison air box to the LH Astro Ventillation ball. It runs just below the dash and has a support bracket that mounts to the 'extra' hole in the lower dash pad bracket.
I call it the Jesus duct because until you learn to correctly drive an A/C equipped Shark with manual transmission, you get this syndrome, and it happens ESPECIALLY when you let someone else drive your car… You have to learn to hit the clutch peddle with the ball of your foot instead of the forward center which is ‘natural’. If you depress the clutch ‘naturally’, your toes overhang the upper side of the clutch pedal and it’s a matter of time before you hear this ‘RIPPING’ sound when your toes hit the A/C duct and tear the thin walled plastic to pieces. Of course, when you hear this distinctive sound, you immediately cry JESUS!
The other version of the 1970 AIM is not significantly different than the one produced originally by MidAmerica. Occasionally I will find a sheet that is different, but not often. Each version has a few sheets missing that the other has, so they can compliment each other in that regard. It is significantly better quality graphics, and has the Chevrolet Photographic page headers. I believe the other version was to market before the MA version -- at least I became aware of it before MA's version was out back in the late '70s I think. Back when swap meets were real swap meets (before FleaBay) one could occasionally find used copies of them.
Back to the thread topic:
The 1969 AIM has substantially the same page for the courtesy lamp install -- the same odd shaped bracket and all -- as both 1970 AIMs. Wile I have no wish to drag this thread any farther astray than it has already gone, the 1968 AIM shows the courtesy lamp mounted to the bracket in the same location, but the bracket is drawn in a very different configuration than the bracket of 1969/70.
Occasionally I am reminded by incidents such as this that all the AIMs in the world will not tell one exactly how the car was assembled. Unmolested Corvettes are the best examples.
Now the challenge is, should you chose to take it up, to try to determine at what point in 1970 production the driver's side courtesy lamp was moved from the kick panel to the bracket that was apparently designed for it. Perhaps a quick inquiry into what the location was for 1969 would be in order as well. We should keep in mind that AC might make a difference in where the lamp was located, or at least we need to verify that it did or did not make a difference. Someone needs to take up this cudgel and coordinate the change/amplification of this section of the TIM&JG.
"While I have no wish to drag this thread any farther astray than it has already gone, the 1968 AIM shows the courtesy lamp mounted to the bracket in the same location, but the bracket is drawn in a very different configuration than the bracket of 1969/70."
AH HA!!!...Just as I thought. So are we left to conclude there is NO AIM REFERENCE showing the courtesy lamp mounted on the driver side kick panel?
"Occasionally I am reminded by incidents such as this that all the AIMs in the world will not tell one exactly how the car was assembled. Unmolested Corvettes are the best examples."
I completely agree...But, if you don't have a warehouse full of unmolested cars to scope out, the AIMs will give you something to think and argue about until you can find some unmolested cars.
"Someone needs to take up this cudgel and coordinate the change/amplification of this section of the TIM&JG."
Yep...Needs to be someone that sees a LOT of unmolested cars; probably someone that judges regularly at meets all over the country.

I agree Chuck. When are you going to start traveling more?
Since 1999 I have taught the Advanced Judging School at most regionals and all the National meets. That has kept me away from judging, so it is someone else’s challenge.
