That's a 1400 style panel but if you enlarge the picture you can see the raised portion on both sides are flat panels raised using rubber vibration dampeners. Relatively easy to make.
I personally believe the U-10D panel is the way to go as did Larry Montgomery it is non-symmetrical lower on the right side. It gives you slightly better visibility on the right side while taxiing.
The Helio I know of that has that panel is 1217 and 1251. I will attach a picture also notice the cut out in the Yoke and spring loaded wire bail on the left yoke it holds an approach page right in front of you. I believe 1251 was modified and raised too much on the left side.
I always intended to modify my yoke but couldn't find the clipboard that the wire was taken off of.
I also attached a picture of 1233's panel I made the padded glare shield I also put green instrument lighting under the overhang like is used in some expensive cars.
