What are these dates? 3 speed wiper motors

Can someone tell me the dates?

Or a link to where there is an explanation and I can read it myself.

3466 and 2836 do not translate to the list on the other thread.

With the part numbers beginning with '25', that indicates parts that were introduced in the mid-1960s.

The date codes of 3466 and 2836 suggest fall/winter 1966, so for the 1967 model year.

Do they have a black, 8-blade plug instead of the white, 4-blade than an E-body does, or dual plugs?

[Cuda Cody]

   Yup.  Not e-body.

2587697 is listed in GG's "white book" as: 1968 B-body LATE 3-speed wiper motor

but the dates 2836 MONDAY 10/10/66 & 3466 MONDAY 12/12/66 do not make sense for that   

283rd day of 1966 & 346th day of 1966
