Yes, I like the 70 - 72 style brakes over the 68 style.
The 68 style has the lower spring for the shoes going to the adjusting lever, the 70-72 style has the lower spring go from shoe to shoe and the adjusting lever is by itself...
Get the spring kit, both side hardware kit, and shoes and tell them it's for a 70-72 Duster, Dart, Demon to get the proper parts...
