Simple Definition, Orient Between Surfaces

I need the ribs scaled between the surfaces, while at equal intervals. I did it by manually for the one on the left in the screenshot. I would like to develop a definition to do this instead, since it would save many hours of manually doing it. I tried using boxmorph on another discussion but it didn't work either because of how I modelled it or so other anamoly, it also didn't do it the way I did manually. I am new to grasshopper and would love the help. Check the screenshot for the example, or the file to better understand how I modelled it.

Thanks!
