Update:
Making a little progress. I decided to cut away the inner edge of the outer wheel houses so that I could cut and tuck the rear quarters in a bit (I did that before I set the quarters on). I'm hoping to stuff some 285's back there.
I started by laying down some thin masking tape to mark a straight line.
Then I cut straight lines with my airsaw every inch or so.
I was able to bend each section by hand and follow up with just a little hammering to get the edge to sit flat.
I then spot welded.
Cleaned up with some sanding discs and sprayed a light coat of Zero Rust.
