2 bbl carb linkage set up - ARM or Cable ? HELP

So, I got the Autolite 2100 and one of the classic inlines 2bbl adapter. Now what is the best way to make it work?

Since I have a stock throttle arm ( 66 mustang with 200) is it best to change over to a V8 arm and use a cable set up or what? Suggestions are welcome.

Thanks.

I'm in the process of installing a 2100 on my 200ci engine. Switching to cable is easier.
I bought a lokar pedal online and a 36" throttle cable from jegs.

Hope you guys don't mind me jumping on this thread. I am installing my Weber 38/38 on my 78 Granada with a 250. In order to use my existing throttle cable I have to make a serious S curve with it and it is still not long enough anyway. Fabbing a bracket is no big deal but is there a simple way you guys have used to deal with this? Of course the stock configuration actuated perpendicular to the head. Now I need to pull back parallel with the head over on the passenger side????
