Demon Gas Cap custom options/builds

someone on here did modern car door handles and fuel door on a Duster that were oval shaped and it looked killer. i think he said he used chevy stuff from a junk yard car.
something like this,
Hagan Street Rods 90OVQ 90 Curve Series Fuel Door, Oval | eBay
i think he did it to remedy spilling gas on the quarter every time he filled up. I have always wanted to do something similar
Be careful! I used the Hagen door and a Tanks gas cap on my 37Ford. It burped all the time and the gas cap couldn't be removed through the door because it was too large. I tried to remedy that problem with chevy stuff but the door opening was too small to incorporate the cap.
