I don't know. YoungGun made it look pretty easy lol. I'm sure my attitude will change after I cut out the first wheel tub and realize I have no idea what I'm doing.
In all honesty though, I think you just need to lay out the procedure and follow the steps.
1- Remove back seat and interior panels, along with the rear section of carpeting
2- Empty the trunk
3- Jack up the rear end, secure it on either blocks like YoungGun did or use like 27 jackstands.
4- Remove the rear tires and cover all of the brake hardware.
5- Ensure that there are no fuel or brake lines near where you will be cutting.
6- Relieve tension on the trunk torsion spring assembly (not exactly sure how this is done, but I'll figure it out.
7- Cut off the bottom of the trunk torsion spring bracket that attaches to the wheel tub (or just drill out the spot welds).
8- First cut out the inner section of the wheel tub, running a straight line from front to back, along the flat spot just over the inner-top crest of the wheel tub, where it will be easiest to add a section of straight, flat sheet metal later on.
9- Then wire-wheel out the seam sealer and cut the bottom seam of the of the wheel tub where it attaches to the trunk/passenger floor.
10- Re-position the wheel tub 2-3" inward, parallel to the edge of the frame rail, ensuring that the trunk torsion spring assembly can still be attached properly.
11- Tack the wheel tub in its new position.
12- Cut a 2-3" section of flat sheet metal to cover the gap betwene the re-positioned inner wheel tub section and remaining section of outer wheel tub.
13- Tack weld the added section of wheel tub in and ensure that everything lines up.
14- Finish weld and seam seal the wheel tub to ensure no air infiltration and no areas for water to splash in.
15- Undercoat the exterior of the added section of wheel tub above the tires (or at least paint it to stand up to the exterior elements).
16- Prime/Paint the wheel tubs inside the trunk/passenger area.
Repeat for other side.
I am probably missing something (and please feel free to tell me if I am), but that is my plan to follow if I end up needing the extra tire space with my new wheels/tires.
