sheetmetal thread(tubs,floor,trunk,tunnel)

[Travis77]

I plan to redo my wheel tubs (inner and outer). Previously I had some made from 18ga that were tig welded on the frame rail side but had no lip on the quater panel side. I simply welded a lip on a 45 degree angle to to form a radius around the quater panel. I could do this again, but looking for a better approach.
My question is, does anyone have a picture of some custom wheel tubs they or a shop have built? All I can come up with is fabricated inner tubs that retain the factory outer tubs. I have a sheet metal shop I plan to take my car to and start building the floor, tubs, trunk, and trans tunnel. I am having a hard time visualizing how and where I want the lip to meet with the quater panel. The guy who owns the shop will let me do all the welding while only paying for one of the helpers hourly labor rate .


This is for a mustang BTW. Had to put that at the very end so I would not lose the readers interest
