I just wrote these directions and I am hoping that some one that has installed these and they might give me some feed back on the accuracy.

Directions for installation of heavy duty wipers for International Scout II 1971 to 1980 SP10201
You have purchased a heavy duty replacement wiper. These are different from the original factory wiper set up. You will need to modify your old arm to make the new wiper arm fit.
Unmodified wiper arm procedure.
Step One –Lift wiper arm and pull back small retainer tab and remove original wiper.
Step two –. Locate post that the original wiper was attached by. (The post the old wiper was hanging onto.) This post must be removed. You will need to drill it out. The post is really just a long rivet.
Step three – Locate the end of the rivet that is bent over by the original installation of the rivet. (It will have a small depression in the middle of the rivet.) That end will need to be drilled out. Use a 1/8th” metal drill bit, or larger.
Step four – Remove the post from the arm.
Step five –Place the new wiper on the arm and keep it in place with the small nut and bolt included.

Step two – Remove old wiper.
Step three – Place the new wiper on the arm and keep it in place with the new small nut and bolt included.
