46 47 48 Fleetwood and/or AeroCoupe

was looking into fender skirts for my 350Z.
found a pic of a pair that look like they might be close enough to rework.
Asked the seller to measure them but I get this brain dead response
"I wouldn't know if they could be modified to fit anything else".

I didn't even tell him my application, but thinking they would look real art deco

I replied as patiently as I could "you can't measure them?"

definitely not a car guy- probably doesn't know if its a Chevy or...

would anyone happen to have one (46-48 Fleetwood/aero coupe) they could measure the rear wheel opening?
