Inner wheel tub replacement
 

Working on getting the rust taken care of, I've removed a big part of the quarter pannel and found I needed to replace the part of the wheel well that sits behind it. I can't figure out if I'm missing something simple but I've removed all the bolts and don't see any spot welds on either side. Does anyone know how they come off?

Can't help but I am curious too and here's a bump for ya.
