Do you mean the blades or the wiper arms. I have a set of arms, mail me at pfmengel@yahoo.com My arms came from a 72 Comet GT.
All of my old fords have 80s ranger arms that i cut down. This gives the modern pin mounting and lets you get blades anywhere. The splines are the same, you just have to pull them apart, cut and drill for the spring& rivit and put em back together.
