i just did the swap on my 85 vert,you dont have to change lower control arms.your stock ones are fine just get some aftermarket castercambers and it will be fine,i used 98 v-6 spindles with 03 cobra front brakes and my wheels fit great in the wheel well,as far as the back goes i used lincoln rear set up and had my friend weld the caliper braket in the stock location for a mustang track width.i used the rear stock mustang lines and flared them to fit in the lincoln hard lines
