Dougs installation problems on '74 Duster

I have a 4 speed 70 Dart, does anyone know how they would fit on that?
I'm thinking about breaking open the piggybank on a set.

They fit well on the car.

One area that you'll be doing work is on your Z-bar. Both Dougs and tti are horrible for fit on the downside leg of the z bar. Every car I've ever worked on required moving the leg or a major bend/grinding with those two header brands.
