No reason to be sorry at all. I was just surprised to see it....:)
For what it's worth....The white bushing I pictured & used for my car is for a 2-speed wiper motor. I had alot of trouble getting the linkage correct too! Best of Luck :thumbsup:
The P/N for the white one is 2580200 the 1970 parts book shows it for A&B bodies variable or 3sp depending on the switch.
The black one is P/N 2631766 and is for 2sp motors. I have about 50 2sp motors and none have that white bushing.
