So, I recently swapped in a leather interior in my car. Got all the seats, steering wheel and leather shift knob from the donor car. The only thing I did not get were the door panels. They were too far gone and damaged to be used. I was wondering if anyone has ever done the inserts in the door panels in leather? If so, how was it done? I think they are plastic welded in place if i am not mistaken. Any input or pictures of this being done would be much help. Thanks!
