Carburetor linkage Questions for 67 Dart

My carb linkage geometry is all jacked up and I need advice on how to proceed to fix it. The Transmission kickdown has never worked since I bought the car and now I would like to fix that too.

So I'm looking for an integrated solution.

The carb is a 1406 Edlebrock 600 CFM. I could use help identifying the intake manifold if anyone recognizes it.

Attached are pictures of the carb and linkage.

Any advice would be appreciated.
