Topic: 67 starter solenoid pics

[preaction]

This is the one from the car as I got it and IIRC it was sticking  from lack of use, the AMK was an A2

In a very rare cases you can also find the plastic bottom (different supplier using the -A2 marking) solenoids used during 67 or even a C6 (hard to find) marked on during the early months

As you can see the plastic bottom one was produced by a different supplier which may in turn reflect the assembly plant they can be found on (cars from that plant on a very rare bases IMHO). It also uses a different finish in the mounting base 






If you check the bottom of your original you should find a date stamped them or metal bottom ones as shown below





A shot of another one like yours - have studied these for a long tiem

Jeff, the number and letters stamping on the bottom plate, would that be a date code?

If they are date codes,
7DC decodes to: <fill in the blank>  (my stab at it: 7=1967, D=April, C=third week)
7HA decodes to: <fill in the blank>  (my stab at it: 7=1967, H=August, A=first week)

Yes as mentioned above. Not sure of the third digit at the moment - will check to see if I have an records of the last letter being greater than "D" If so then it would decode differently for the last part

If the third character actually does represent the week, it seems there would also be a 5th week, or letter "E" possible (most some of the time~edit per Jim's next comment below) or does that somehow roll into the following month as the "first week"?

Somewhere I read that the production week started on a Monday. A 5 week month would have a maximum of three working days in week 5 so parts marked "E" would be relatively rare.

Would guess that it might be a general standard though might differ from manufacture to manufacture.

Only research and data will help us figure this out - I expect

I did a date analysis on three years, 65, 66 and 67, for working days in a possible fifth week.
1965 had four months with fifth work week days: March - 3, May - 1, August - 2, November - 2.
1966 had four months with fifth work week days: January - 1, May - 2, August - 3, October - 1.
1967 had three months with fifth work week days: May - 3, July - 1, October - 2.
I did not consider holidays, weekends or plant closures. The number of days is maximum, no more than 3 in any fifth week is possible no matter what day of the work week is used as a starting point. There will be a maximum of 4 or minimum or 3 fifth work weeks in any given year.
