Inner rear quarter pannel??

I think pounding on that and you will ruin the quarter real easy.I guess you are set on wheels,and tires,so I won`t go there.Ever thought of just raising the rear of car alittle,maybe get 1" over stock springs?This worked on my Valiant,when it was rubbing .Looks like you have billet wheels,is there anyway of having a machine shop take about 1/2 inch off the backside of the wheel face?
