The 79's had more emissions controls and sensors / thermostatic switches on them to control aspects of the emissions system.

I would have to consult the service manual to properly remember what all those are.

or Dan or Mavtv91 will chime in.

Did you get this arm, they different from one barrel to 2 barrel.

Yellow dots D angles clocking to shaft are different

That was an air conditioner car, mid-year running production change on the carburetor, solenoid for idle and a different throttle bracket on a carb. Any other air conditioning brackets left on that car. Throttle return spring bracket also used for air conditioning mount. Was it a sedan or wagon, carburetor tag number still there? Blew up your picture looks like you still have conventional idle screw and solenoid

Great info, I was going to ask if anyone had the 1979 manual. This is from a 4-door sedan, with A/C compressor still mounted on it until yesterday. I haven't had time to read all the manual pages you posted, but it looks like I wouldn't need that choke switch if I get one of the adjustable choke controllers Dan likes. I can take better pics this weekend when I start disassembly/cleaning. I should be able to go back next week and get whatever other parts I need.

On the kickdown linkage, I got the square piece with the set screw, but not the bracket with the D slot. That'll be on my shopping list when I go back.

There's a biggish bracket just above the EGR valve that I didn't recognize, looks like it might have been for the A/C.

Is this the A/C bracket where the throttle return spring connects?

Think so yes

The air conditioning bracket replaces the standard bracket, now that's the later-model round compressor not the old cast-iron V2 .
