Those would be your vacuum advance modules. Keep them, or gas mileage and performance will suffer. Although, I don't understand how they could be interfering with your power steering? Of course, I've never seen a 7 with power steering either.

What lines would you need to reconnect/rerout to vaccum ports? and how?

I personally prefer to use the vacuum port farthest forward at the base of the carb. This will increase the advance once you tip into the throttle, which adds a nice little boost of torque at mid throttle. Use a "T" connector to join the two lines into one, then on to the base of the carb. Try it, you'll like it.

OK.. im a lil tired and confused lol... Your talking about the 2 vac advances on the distributor for the first gen cars right? And putting on a "racing carb"? If so im almost 100% sure that none of the performance carbs need/can be hooked up to them... I just ran a 2" hose from one to the other as per racing beats instructions...
