the back fenderwells on my buick are rotted out.i cut the rear fender wells out of a 1969 skylark.i cut them out about 12 inches around them.they are in good shape.the inner rear wheelwells on my car seem to be o/k.would these work o/k to have a body shop weld these in my car for a repair or do they sell just small replacement panels for these cars. thanks tom
