Its how the piece was made originally. I would ask custom stereo and interior shops if they know anyone doing it.. Or, youtube some videos and try your hand at DIY.
Never done it myself. Just sharing info.
Anyone have the factory measurements for the holes on the front fender for the RX air dam?
Maybe a picture of the service manual page?
Winged it on my current fender and it never looked quite right. Now it's dented and I have a clean replacement. Looking to do it right.
