I have stripped so many 71 bbodies , I dont know whats what . How do I determine if I have a three speed setup and motor . I dont want to mix match ..

Thanks, Sincerely ignorant

pretty sure this is a 3 speed wiper motori want to use - anypics of linkage thats appropriate?

That is a 3 speed wiper motor.
From the blurry part number it looks like one of those
nos 75-77 motors from Volare Aspens that are always for sale.
It will work but will not look correct for 71.
If you are going full original you would need one like this.

Your linkage should look like this.

and your cam should look like this

Not Very interested in looking correct , pro touring project . Must unorthodox 71-72 Hybrid car non matching car ever .. But - THANKS for info on linkage .. Now I know where i can get parts

i have this which is one digit off from yours

and the cams look similar , but the bushing on the drive arm ? is yours missing something ?

Your linkage is a 2 speed with a 2 speed cam kit and it will not work with that 3 speed motor you have.
I have a 3 speed linkage and cam kit for sale if you are interested.
You must also check your dash switch.
If it is a 2 speed , it will not work with your motor.

ok i got a 3 speed setup , funny , I figured that the more complicated one would be a 3 speed

Now , it should be easy enough to identify a three speed switch , i am assuming three clicks on the switch .. Is every rallye dash harness created equally with wiper wiring ?

A 71 B body has a variable speed switch.
One click, then a rheostat type sweep.

"Is every rallye dash harness created equally with wiper wiring"

EVERY is a big word. If you have a 71 dash wiring your plugs will look like this.
Jules

i definitely founda rheostat switch , thanks .

So I am assuming that the dash wiring is same no matter whether 2 speed OR 3 speed

Thanks

The wiring is the same.

Thank You Mr Wiperman , I appreciate your help ..

You're welcome

JulesdaWiperman you a are the best

Thank you.
Only trying to help.
Jules

Yep Jules is the wiper guru I guess the give away on the later version wiper motor would be the plastic cover instead of the flat steel piece, am I correct there?

Yes, early 72 and on.
