That vacuum tube route in that picture would not be applicable to your particular Shelby application .  The delete sheet was for a series of Shelby cars built all the same way (with the exception of color)not your particular car like a conventional build sheets. I have yet to find or hear of a conventional build sheet found in a 67 Shelby although it was no out of the ordinary to find a add+delete sheet in one. They were typically found in the car under the carpet.

I doubt very much previous owners would have left the add/delete sheet while they had the interior apart.

Which picture would be incorrect? The two I posted?

Just posting where they are found and not commenting on the possibility of finding in your restored car. The rear mount valve in Jeffs reply #40 that you commented "wow" on.

I thought Bob posted a picture comparing 67' and 68' thermactor tubes but I can't seem to find it now.

I am looking at pictures of 67' cars and I can't see the difference in their tubes and these;

I am sure Bob or Jeff will straighten me out.

The quickest IMHO way to take note of the differences is illustrated in the following two pictures. Top a 67 design the lower a 68-70 design. Hope this helps

On the 1967 left side GT500 thermactor tube is there a support bracket? The pictures 2112 posted I can't see the bracket...
