Welcome to the forum, dually dude!

I am guessing the part you described is the EGR adapter. It is made of aluminum and is approximately 1" thick. The EGR valve mounts to the side of this.

I just need to see where they go into the manifold.

When I get more time later this week, I'll start to re-connect all of the vacuum lines I need, and get the new carb installed. I will update this thread once I do, and I'll post some more pics just because. Thanks again!
I think it was the older style gas petal linkage I have a 1983 Ford F-150 with a 4.9 300 I6 and have the same linkage I was going to take mine off

From there the filtered air, now hot because it passed through the chamber, routes up to the choke cap through the hot air tube, which is insulated to help hold in the heat.

These tubes typically rust off and break in the holes of the choke stove chamber, making removal of the tubes very difficult. You will have to remove the manifold to get the broken ends out. Or you can go to any auto parts store and ask for a Choke Stove Kit. They can usually be found in the Help! section.

Amazon.com: Mr. Gasket 3665 Choke Stove Kit: Automotive

It comes with a length of coiled up aluminum tubing that you can easily bend by hand, the hot air tube insulation, the hardware to mount the tube to the choke cap, and a little "dome" with a hole in one end for the tubing to push into. This dome acts as the choke stove chamber and clamps to the exhaust manifold or header pipe to trap the hot air when the engine is running and routes the hot air up to the choke cap.

The only difference is the universal Choke Stove Kit doesn't use the fresh air portion of the stock hot air choke at all. It is intended to provide outside hot air to the choke. Very simple to install and works great.
So based on what i am reading here. This vacuum that has rusted and broke off for a long time now NEEDS to be replaced. The most simple process would be this kit? And retreiving the broken portion most likely i should takeoff the exhaust manifold to achieve this? Thank you, ive been searching for hours and only came across this thread

There is no easy quick fix for this, but it does need to have the hot air source for the choke to open.

Here are some more links to look at. Be sure to read the whole thread.

You can just leave those broken off tubes there. You will not use them if you use the universal choke stove kit I referenced earlier.

The choke stove kit has all you need to get your thermostatic choke system working again. It provides a new hot air tube, so you can even use it on headers.
