How to remove outer wheelhouse?

They are seam welded on to prevent leaking Between the two halfs so you won't see any spot welds in that area. They were welded together the same as a gas tank.. You'll see a 1/8" wide ribbed seam all along the flange if you look closely.

Danny's method is the way to go because grinding that outer flange off the inner would be next to impossible since there are so many other things in the way while the inner is in place.

I went a different approach and butt welded on what was needed. I think each method is just as labor intense..










Hope this helps.
