Looks like yours are power seats? There will be a problem if you try and swap them as the seat adjustments will be up against the drive line tunnel. I'd look and see if you can find another drivers side seat. Or have the broken seat straightened and re welded.

the seatback tends to snap at the welds on the x bracing.  remove the seat, unzip from the bottom, and slide the foam and material off as one piece.  It'll expose the frame.  The frame will have x bracing that has snapped.  First you'll want to square up the frame, otherwise when you weld it, you'll weld it crooked, such as what i did.  Once it's all squared up, reweld, even add more x bracing for strengthing.

Weld it up get some red vinyl dye and they will look great until you can re- upholster  them.
