'75 Duster B body front brake upgrade impressions wanted

72bluNblu, have you tried any aftermarket brake compounds? I relined a set of the Porterfield R4-S shoe linings on my '63 Dodge M37. These are 14" x 2" shoes on all four corners of the truck. Stops much better than the woven asbestos linings that came with the truck.https://www.porterfield-brakes.com/images/portstrt2008_11_06_02_45_30.pdf
