I have a 2 speed power glide in my t-bucket. I have the kickdown linkage
and the vacuum hooked up to the edelbrock carb. My question is do I need them both?

I think the modulator needs to be hooked to full manifold vacuum. And I would use it and the kickdown also.

p/g

modulator control line pressure,linkage is for shift points,yes you need both.
