Need disc brakes, Nothing fancy

[Tower of Power]

Can anyone let me know where i could go about finding relatively cheap but good big bolt pattern disc brakes for my '72 duster?

Look for a 74 and up duster, dart, valiant with disks. You need the upper control arms and spindle, calipers and rotors. If it was me, I'd get the lower control arms too if they have the sway bar tabs. Time to go Junkyarding!!
