How To Fix Leaking Wiper Pivot Seals

I don't have any pics to help out but on my 73 there is a small retaining clip that sort of arches inward toward the post the arm mounts on, this is on the bottom side of the arm, hard to see at first look. If you have a small flat blade screwdriver, I used the adjusting screwdriver that you get when you buy a new Stihl saw. Use an old towel to cover the wiper arm mounting area and clamp some vise grips on lightly then move the small clip while you work side to side motion and upward force. So with two hands, you need to get about four things going all at once, not simple but possible. Hope this helps.
