Stupid Carburetor Question

Stupid Carburetor Question
I am finally getting around to getting rid of the feedback carburetor and distributor. Have a Carter 1v from an '83 F150 300 and a DUI distributor.
Maybe I'm looking at this wrong, or have the wrong carburetor, but it looks like the heat riser tube to the choke is on the other side (driver) on the new carburetor. My current one, as I recall, has the tube on the passenger side. Also, I don't see the choke pull-off on the new unit. (does this need to transfer from the old one?)
** UPDATE **
I spoke to National Carburetor and they are telling me this carburetor doesn't use a choke pull off? Does that sound right?
Looks like i just need to plumb the new choke tube..
While I'm editing..
What wires can go away after this conversion? There are 2 wires coming from the air pump valve, some from the engine temp sensor and oil pressure sender, etc that are all part of the same harness that goes to the carburetor. Can I just 'unravel' and remove the parts that go to the old carburetor, distributor and coil? I could leave them in place but I'd like to clean it up a bit.
This whole project got moved forward when the truck decided to run like crap all of a sudden. Idles very rough, cold or warm. Checked manifold vacuum at idle and it only about 13 or so and fluctuates.
Argh....
Has anyone else ran into this and, if so, how did you deal with it?
I'm wondering if I need a different carburetor or if I need to fab some sort of tube to connect it (not really sure what that would involve..)
Thoughts anyone?
Thanks in advance

That doesn't quite look like my carburetor. The old one has a vacuum choke pull off mounted on the driver side.
The new one doesn't have that. They said to just plug off the old vacuum line. Speaking of which, what port on this carb should go to the new distributor vacuum advance?
My current one looks like the one below:

If you remove the engine computer, the EGR and evaporative emissions will be rendered useless because they were computer-controlled, so you can remove these items. You will need to use vacuum switches if you wish to have these devises functional again. All engine sensors (O2 sensor, MAP sensor, etc.) can be removed as well.

The wire harness is a friggin mess; connectors all over the place, what look like solenoids and relays, etc.
Would it work to just trace and remove any wires that where plugged into the computer unit and leave everything else?
I suppose the wiring could stay, but I'd sure like to clean it up. I just don't want to remove something I need.
In terms of EGR, I didn't think that was computer controlled, all I see going to it is a vacuum line. Is there a control solenoid somewhere? It looks like there is a bank of relays / solenoids mounted on engine (top, rear, driver side). Do those go away?
Is EVAP the charcoal canister or ?
What about the smog pump? Is it controlled by the computer as well?
