Looking at RockAuto, the 72-up wiper motors are $40.
70-71 is not available, and from what I can tell it's >$300 to get rebuilt.

Anyone know what the difference is, and if the later part can be modded to work?

I have ran into the same issue I also need one for a 70. From what I was told the difference is that they park in a different place. The 70 will park lower for a hidden wiper effect. But I do not now for sure if this is true.

For what model? 2-sp or 3?
70/2E and 71/2B til 9-71 had veriable speed then 3-sp after that.
Bet RA 72 is not correct either.
Stating in 73 all -3speeds had a plastic cover

Yep just checked. Their 72 3-spd is a 73 and up.
71 didn't come up.

I'm just looking for the cheapie 2-speed for a 70.

They all have the same hoods, so the lower park position doesn't make sense.
I'd guess the wiring harness is different.

Hoping someone has gone through this already.

the diff between 3 speeds and variable is actually at the switch not really at the motor

Dunno what you mean about "plastic" cover

the diff between earliers and lates at least on 3/var speeds is lates have a "tower" on cap ( maybe this is what you meant about the plastic cover ? ) for the parking and turn off switch, and earliers are flat

Hi Nacho
The motor in the upper pic has the plastic cover over the wire connections, thats the 73-up style.
Lower one has resin thats the 72-down sytle.
Heres the early 72B/E 534 V-spd.

You need a 929 2-sp which fits 70/1E, 71B 69/71C

Ok, we're getting closer. In the 2 pics above, the connector looks the same.

So why (or what needs to be done) can't I use a 73 model.
I can buy it from RockAuto for $40.

70 version is NOT avaliable. Hoping to not pay $300 to have it rebuilt.

Hi Mark!

yep I guessed that was what you meant

HOWEVER I mounted a 72 3/var speeds on my 74, and it has also the plastic cap/tower. Maybe a mid 72 year change ?. I can grab the PN around

HONESTLY ? I think all 70/74 E and 71/74 B motors are TOTALLY interchangeable. Diff stuff is a correctness deal

Post an ad in the parts wanted section. I ran into this when my wiper motor quit on me. I never did get a straight answer on how to adapt the readily available wiper motor to work on my car. So I put a parts wanted ad and recieved responses really quickly.

Didn't 72 use the clip for the wiper arm and the 73 use a nut ? My 72 Challenger 3 spd motor uses the clip and my 73 Roadrunner 3 spd motor but I'm pretty sure it uses a nut for the wiper arm.

I was thinking on that as a posibility HOWEVER, Once I got a NOS repairing kit and on instruction sheet never said something about the year, and included a big list of wiper motor PNs including earliers. The kit included the threated shaft.

I would say really the clip its at CRANK side of main linkage and not to the motor shaft side

The 71 and the 72 are not a straight interchange. The crank to wiper lingakge are a little different and if you use a 72 motor on a 71 (or vice versa) it won't bolt up to the crank arm. The 71 is the last year for the red epoxy on the front wire, the 72 is left bare (I think they put a plastic cover after that). The direct cowl boltup is the same, and the wire harness is the same. Two speed switches will not work on a var/3 speed, or vice versa.

Mo Mopar was horrible on the interchange between years in the 70's. I'm sure it had to do with sub contractor suppliers.

Even a different crank between the two 72B/E V-spd #534 and the 3-spd #624.
Also both these 72 motors had resin or red epoxy.
Again 73 was the first year for the plastic cover.
70-2 linkage has brass bushings and the big round clips.
73-up had push in nylon bushings.
Very little will interchange or work between 72-down and 73-up.

The 3431624 is a 3-sp and does not have the black cap.
Heres the one that came on one of my later 72's. Have had several more just like it.
