drum to disc O.E issue

i do NOT want to go to lbp! i need to stick with sbp because im keeping the wheels i already have. the only wheels i want on my car are either the ones i got (dish centerlines) or some mopar rallyes down the road. thats it! changing to lbp is WAY more expensive for me. then id have to buy new wheels, tires, ect. wheels and tires alone would be $2k
