Can I use a different model to replace the LCD?

Okay, I have the Verizon version of S4 SCH-I545. The LCD needs to be replaced. I also have available a working LCD from the ATT I337 S4 which includes the frame. I read that they have different frames and home flex so you can't just use any version to replace LCD.Can I just switch the LCD to the Verizon model motherboard?.Do all the motherboards match up? Can I just transfer all the parts to the I337 LCD frame? Or is the home flex connection different on the verizon motherboard?
