Well, since I also fly a yoked airplane (182), I bought the hardware to work for either situation. Here's the list of parts I bought from RAM:
1)
Yoke Clamp Base with 1" Rubber Ball and 1/4-20" Tap for Camera or Video
2)
3.25" Diameter Suction Cup Twist Lock Base with 1" Ball
3)
Double 1" Ball Adapter
4)
"B" (Medium) Arm
5)
"A" (Short) Arm
6)
iPad Cradle
7) Two 2.5"
2.5" Round Base with the AMPs Hole Pattern & 1" Ball
So - Obviously I'm not using the suction cup and the yoke mount at the same time, but all the rest of the parts are in use. Here's a top view of it mounted in the DA40 which shows the double-ball connector and both arms a bit better:
Having two arms and the double-ball connector allows for a lot more positioning flexibility, so it works in both the DA40 and the yoked airplanes as well as my car.
In the 182, I use the yoke clamp, then run one arm from that towards me, and then the ball and the second arm allow for it to "bend" down over the front of the yoke so that the iPad is centered better. That should work well in the Cherokee too.
