I have a 68 coronet with drum brakes. I would like to swap to disc brakes. I found a 73 charger in a salvage yard with disc brakes.I noticed that the lower control arms,spindles and ball joints were different. Can I swap all these parts onto my 68 without screwing up the steering geometry? Do I have to use the upper control arm off the 73  also? I would like to use a kit from SSBC, But I just dont have an extra 1,200 bucks.  Thank for any help.  

my only answer would be to ask the scrap yard to look into their hollinder book on interchangeability,good luck  

ok bro, heres what it boils down to, you need the 66 to 69 belvedere,satellite or charger as the knee assembly wont work on the 68, this is assumming a v-8 engine and no sway bar.knee assembly hollander # 510171,front spindle,515540,lower control arm# 512709A upper control arm #511455 knee assembly #510171,using an old rotor #5301219,used caliper#536103 v-8 cross member #4772553.these are the hollander numbers I looked up for you but basically no the 68 wont work. just find a 69 charger,belvedere, or satellite with discs and your in business. know these cars arent everywhere but look around.easy jobonce you find the donor car,take care  

sorry friend a 66 to 69 belvedere,charger or satellite is what you need.take care
