I have a two speed wiper motor and electric washer pump set up on my 70 b body, my wiper motor went out and i was looking to replace it with a aftermarket unit from auto zone. However they do not sell a unit which has the setup for the electronic washer pump should i just bite the bullet and install the new style unit? I dont have the washer bottle currently but i thought about it soon. What other options do I have besides the 3 speed switch over thats expensive.

on a 70 B-body the style motor has no bearing what so ever on the pump style OR vice versa.

find a different parts store

Tony,
If you shop at AutoZone because they're handy
that's fine, BUT before you go to the store
go to their website & look up the part yourself.
Get the p/n and usually if it's in stock.
Autozone lists a reman motor #40-350 @ 46.99 ex.
(in my area)for a '70 b-body.
The note on the washer pump must have been
added by a gm person. Like Bill said wipers &
washers on Mopars are independent.
