That would suck !
No one around there has even a styleside, I don’t think it has to be an EDGE; you could match them up by eye.
Look at the side of the styleside and see if the creases and rolls are located close, maybe take a tape and check.
How about one of those Trim measuring devices with all of the fingers, hold it up, make a copy of the more curvy areas and have a go at it.
Measure the ID and opening and the same area on the flares.
Buying the EDGE Flares, unless cheap, is a good idea on one level but too bad on another.
Any Ranger Owner in B.C. Canada that can help this guy out, who has a Ranger EDGE or any styleside with, maybe with flares.
