For what it’s worth, I don’t believe that bolt was for a 67 option. Ive seen it on too many 66’s.
My car didn’t have it but someone had changed from the original carb to a Holley. So it could have been there originally. The parts car had one and had the original carb. Same as Otto’s. My parts car had the transmission line attached to it but I know that wasn’t right because the metal tube was all bent around to reach it.

My personal opinion is that it doesn’t matter. As long as you have vacuum where you need it and ported vacuum to the distributor and all the others plugged you should be good.

Since I’m putting the original carb back on mine I’ve been looking for the Same info and I don’t think it exists. There were too many options and too many variables.

Just my two cents.

Ok thank you Otto and Tuco, this is what I found so far...
We all agree that the transmission line goes to that green input where I have a tee. Dashpot for the throttle goes to intake vacuum, so either on a plug at on the intake manifold as shown on the diagram, or to the red bolt that we have on the back. But it seems to need a check valve and I don't understand why... maybe to have a slower release ?
Then comes the subject of the distributor vacuum advance, many many websites are arguing about the fact that it should be plugged to the direct vacuum and not a ported vacuum https://classicoldsmobile.com/forums/general-discussion-33/ported-manifold-vacuum-advance-113536/, as it seems to make more sense to me, I'll just keep it that way and let it on the tee. I found a diagram where it is connected to the ported vacuum, but that's with the K-19 or K-20 option. Sadly I can't find one in a normal configuration.
So it seems like the ported vacuum on this carburetor is not used, as on many of the 7026250 it is either not present or plugged.
My goal here is to have a reference for anyone who wish to work on a Toronado and have everything right the first time So your contributions are more than welcome.

Hi Francois,

I've never owned a car that doesn't have a carburetor.

All the vehicles I currently own have the dizzy advance coming out of a port on the front of the carburetor. '56 Cad, '79 F 100, '66 Toronado, '64 Galaxie 500, '76 F150. And as I recall, my '66 Mustang, '72 Monte Carlo, and '68 Camaro all had the vac advance coming off a port on their carburetors

My '66 Toro did not have a dashpot when I bought it. I've never bothered installing one and I've never had a problem. I considered adding one after the Q jet was rebuilt but there is no bad effect from not having one.

Thanks François. Good info.
