Straightening or replace the frame

I've got an iPad Air (a1475) with wifi and cellular. The frame is bent on the side wall and bottom as it took a really hard fall. I can find replacement frames for the A1474 but not the A1475, are they similar enough to use the A1474 frame. Without bending the frame back or replacing it with a good frame, the digitizer replacement is going to be pretty useless.
