These parts where pulled from a 75 Dodge Dart A body car. This is the big bolt pattern 5 on 5 1/2. This is what you need if you want to put factory disc brakes on you drum brake A body car. These parts are quite heavy so I can ship these in a crate via Fastenal. Obviously you will need to replace the lower ball joints & rubber brake lines. $400 plus the shipping which you pay directly to Fastenal.
