wiper motor arm

[plantman]

Is there a difference between a 1971 Cuda 2 speed wiper motor arm and a 3 speed wiper motor arm?

Thanks for your help in advance

Yes is a difference, on the section that bolt with the wiper motor is different.
Will not fit

340 shaker hood install

I am converting to shaker hood, bought shaker parts from Tommy the Chiro. The pan is hitting on my 2 speed wiper motor. So I am converting to 3 speed motor.

Question about getting the wiper motor crank and arms.

I understand I need the Crank #: 2822289 & Link #: 2822293 and I can use my existing wiper arms.



Below is a link to an ebay listing, can someone please help me verify this set up is what I need? The link says 2822293 on it, but the other parts don’t jive. So basically I would be paying $300 for just the 2822293 arm. Can you help me figure out if this is what I need?

Most of the bits are different. The 3 speed cars also had electric washer pump. Have a look at the Bill Meerholz Restorations website to see pics of what you need.
That I know of - and I may have forgotten a piece. To convert properly you need :
3 speed wiper switch
Wiper motor
Wiper motor crank arm
3 speed link arms.

I've done the conversion on my car and coached a guy on his too. Steve340 is right but you only need one link, not links. Listed below is what you need, the pivots and the link between the pivots is interchangeable. This is for 1970 & 1971 cars.

Wiper motor - 3431077
Wiper crank – 2822289
Wiper linkage – 2822293
Variable switch – 2770380

Changing the washer reservoir (+ electric pump) isn't necessary but it does complete the whole thing. You can continue to use the foot pump if you don't switch it out.

I noticed the eBay linkage setup is sold, did you get it?

hey, thanks for the help, i didn't buy that ebay listing becasue i wasn't sure it was correct. it looked like half 70-71 and half 72-74. i just wasn't 100% confident.
