70 2 spd wiper motor part numbers on tag

Replacing my broken 2 spd motor with the unit on the left. I checked the part number on the tag to the parts catalog and it doesn't come close. The part number on tag is 3431730 - and 1614 just above it. Looks identical to the original that didn't have a tag or was not put back on if/when the resistor was replaced before I bought her.

Did I find the correct unit? And what does the 1614 number mean, is it a date code?

What does it all mean? East

164 th day of 1974. Any two speed motors for 1970 cars never came with an aluminium tag with part number and date code. That tag was introduced in late 1971 model year, about April 1971. Part number is: 2926 929. They are identical on A,B and C body cars of that vintage. The tag is always red with the 2926 929 part number and date code on it.
