What's your 3 Speed Wiper motor date?

[Cuda Cody]

Do you have a 3 speed wiper motor on your e-body?

1970, 1971, 1972, 1973, 1974 Cuda and Challenger (E-Body) Wiper Date Codes only.  This can help people when they are missing their original wiper motor and want to find a date that should be correct for their car. 

Dates are shown as 4 digit numbers on the wiper motor. For example, 1170 would be the 117th day of 1970. SPD is Scheduled Production Date and is found on the fender tag. For Example, 917 would be 9th month and 17th day (Aug 17th) of the production year.

Post your Wiper Date / SPD and I will update the list

Could the intention of this thread be clarified?  Are you looking for members who still have their original 3 speed motors on their cars, or just want everyone to post what they have chosen to install regardless of if it was the original one or not? 
I have 3 cars with them, on each I installed a wiper motor dated a month or so prior to the car's build. But sadly none of the cars had their original parts on them when I bought them, so my choice was just an educated guess.
Working in manufacturing I can tell you their has always been variation on when parts are received and when they were installed.  Unless you have your original or documentation of what was on it, you will never know, so like me you try to find one dated 4-8 weeks prior to your build date and call it good.

Great question @JH27N0B   For this database it would be best to only include original 3 speed wiper motors that are known to have come on the car.  It's just a fun way to help anyone who might be missing their 3 speed wiper motor find one that would be close.  Some people will never care about the dates and that's perfectly fine, but for those that do want to know what would be most likely a correct date for their car this database should be helpful.

The database list in the first post has been updated.  It's starting to paint a nice range of what dates fit what cars.
