New rims/tires rubbing I NEED HELP

I just installed the magnum force racing 2in dropped spindles on my 71 plymouth duster with willwood drilled and slotted 12.19 inch disk brakes, I ordered American racing 16x7 torque thrust II's. They have 4 in backspacing. Im running 225/55/16's and Now there are rubbing against the inside of the upper fender well and the back of the tire iss rubbing against the front of the fenderwell when i turn. Anyone have a similar combo or ideas? I cant post pics till tomorrow or monday. I can buy new rims if I have to but I would prefer to make these ones work as a 700$ hit in the pocket is gonna make it much harder for me to buy a house this summer. Should I do more back spaing or what? I found a tire that will drop my diameter by 1.75 in but I dont think that will be enough, maybe, but for 300 for two of them Im thinking I might as well get new rims. This is only for the front btw.
