In about the same predicament on my 73, i do have the arm the that goes over to the d-side wiper, but nothing else ...does anyone have a good schematic/picture of the related parts needed for the 73/74 wiper linkage ..?
Yep the link and main arm are are different between to two.i think 2 speed, but not for sure...I'm assuming by your post that there is a difference in the linkage between the two..?
