Adapter between an Edelbrock 2101 and 1406?

[mrein3]

I have been collecting parts all year for my 383 project.
I purchased a new in the box Edelbrock 1406 carburetor this spring. This week I purchased a new Edelbrock 2101 intake manifold. The counter guy insisted that I need an Edelbrock 2732 adapter to bolt the carb to the manifold. I didn't want to doubt him because I didn't know...
...and it was less than $10.

Do I need this adapter?

The description on the carb box states:
"Square-bore Adapter Plate for Spread-Bore Manifolds - #2732
For installing Edelbrock carbs on some Performer manifolds for GM applications."

I think I don't need this adapter. Especially when I set the new carb on the new intake.

For you folks that are running this combo do you have an adapter in between your carb and manifold?

While I'm at it how does the solid throttle linkage (not cable) work? Any gotchas there?
