2spd to 3spd wiper linkage?

[PettyBlue72]

Is there any difference between the 2spd and 3spd wiper linkages for a 72 B-Body? I am thinking about converting my RR to 3spd wipers and I need to know if I need any parts other than the motor and switch to complete the swap.

Thanks in advance,
Joe

Can anybody confirm if there are any differences between the 2spd and 3spd wiper linkages for 71-74 B-Bodies? I have heard in the past that there are differences but I don't know what they are if any. Picts would also help if the two types are different.

All I have is a 74 chrysler parts cataloge from dealership,it shows that the variable or 3 speed wiper link Part # 3431663 and part # 3431647 fits 74 3 speed models R and W. The 2 speed wiper link is showing part #3431646 and part # 3431684 for R and W Bodies .So they are different Links. I do not have a 71 72 or 73 Cataloge but I would just about say they are the same ones 73-74 3 speeds. If you have yours out, see if you see a part # on them. Had mine out the other day because of wobbling, plastic bushings gone so saw new set and bought them and new clips. ( 2 speeds are different). Hope this helped you some. I would think 71 and 72 would be the same tto, but not sure. Its a BIT_H working on em.

Just put new plastic bushings in my wiper regulator arms, it works like a dream.
