how to split this part

Hi,

I am trying to split this part into two, I have learned how to split using an extruded surface, problem is the front, and back of the part are different shapes (sketch24, and sketch25).

I tried to create a lofted shape, but I can't do it to coincide with the intended cut line.

I am not even sure if I have the right approach.

Thank you
