I would take them back and find a set of shoes with the proper length on the secondary shoe. The factory made them that way for a reason. The primary shoe forces all the mechanicals to rotate the shoes into the anchor bolt, which is a positive stop. The secondary shoe should be fully lined. Interestingly enough, when I bought my brake shoes from NAPA, all four shoes were fully lined like I expect the secondary shoes to be. Strange. I have a D60 in my '70 C20, as well.
