I was wondering about cutting the outter house off, i was just concerned about welding sheet metal to the quarter and how that might affect the quarter, access the weld etc.
I didn't weld it to the quarter, i just seam sealed it to the quarter and it's pretty strong. I have heard of people bonding them with epoxys but since my car is already painted that wasn't an option. It feels strong and this way if something his the tub hard enough i can just re seam seal it, i would be afraid of something to strong there and buckling the quarter if something pulls on the tub.
