Editing extrusions

How can I edit the height of the black extrusion to match it with the red one?

I can’t get the points to stretch. Is there any way to add points and edit the surface?

We can’t really say much useful just going by that picture. Please upload the 3d file.

the two extrusions have to be similar, but the grey extrusion is slightly higher than the red one. Is there any way to edit the grey one by using points or by adding points? I want to know how to edit extrusions because it doesn’t work like curves.
