1968 SS Dart in progress

No material needs to be taken out but when the inner fender is pounded it should definately be done prior to welding inner fender to outer quarter as to avoid severe concave of metal!!! Once your outer quarter is cut leave approximately 2 1/2 inches of inner fender housing (wheel housing) exposed beyond your quarter cut. That way you have enough material to trim back, heat, bend, and tack into place. Also, the use of a good 4 foot level is a must.
