Starship 55

Hi All, First post after re joining. Had an old account when I had my KE36 Pano years back. Anyways, I recently got myself a KE55 Fastback Coupe project that will need some rust work. There is a bit off rust on one of the Rear quarter vents. Personally I've never liked the look of the boxy and oversized rear vents. And never really understood the function of them, i'm assuming its because the tank is in the boot. I was hoping anyone has welded and smoothed this vent area as id love to see what it looks like. Also I understand the point of keeping the car original, I would if it was being kept stock, however its going Sr20 so might aswell personalize it to my tastes. I'm just wondering if its too much of a defining feature of the car to remove. Thanks all,
