tires sound like what happens out here in the southwest. Are you going to put the originals back on the car? Does it have disc brakes or drum front brakes? If it has original 4 piston disc you will have to start looking for a four bolt lower ball joint. Reason I know is that I owned one for several years but was wrecked in 2003. Other wise you will have to get a complete spindle and stuff from a 1970 to 1973 Chrysler product.
