I have 1981 Malibu with a 10 bolt and i can't seem to find a cheap way to get my rear tires to quit rubbing . I'm running a 275x 60 x15, 3.5 back spacing air bag on the passenger side rolled both wheel opening lips and also tried coil spring spacing blocks . still they rub. I'm trying not to have to buy new wheel right not plus it hooks real good the way it set . This all new to me I've only had the car a few weeks.
