Jim, i was looking at your wiper linkage deal. I have a 69 cuda i am collecting up parts for to do a resto w my son. It has the same black clips as yours does. I hunted down a complete wiper linkage assembly and wiper arm pivots from a 67 for his 69. The 67 linkage setup was a 1 year only deal but will fit all the way up to 1976. It uses bronse bushings that are brazed into the linkages, with oiled up felt washers, and metal clips to hold it together. I believe they abandoned that for 1968 up cars to save on costs, as nylon plastic that snaps together is easier, faster, and cheaper on the assembly line. Plus it would work well enough to get the car out of warranty. You may want to concider that setup for the duster. Any 1967 A body would have this setup i described.
