I have 2 bad driver front seats that I can make 1 good seat out of. I want to know what you guys think is the best approach.

Seat 1: Bad seat bottom cushion. The leather is torn where the driver butt goes, but all the motors working fine.

Seat 2: The motor/gears for raising the front of the seat is broken. Motor turns and makes sounds but the seat doesn't move. Raising the rear of the seat seems to only move the rear left corner and not the rear right. But the leather is good.

Is it easier to swap the seat bottom itself from Seat 2 onto Seat 1 or swap the motor assembly from Seat 1 onto Seat 2? I've never taken apart seats before so I don't know what I'm getting myself into. Is this a huge undertaking or not really?
