Widning the rear quarters "all stealthy like",how

[LumberJack_Jim]

hi

I saw this pic of a very neat way of getting some extra rubber room on the rear quarters without ///Ming them or using some nasty looking arches.
They managed to pull the sheet metal outwards!
Does anyone have some more info on how this is done and what bits require chopping?

Thanks in advance!!

looks like the inner arch has been cut and rewelded by looking at the weld patch inside the arch!

Is this the same trick the Bootyman's using on his car to run 11" rims...?
