There's s surprising little about this, for 68 the assembly manual calls for a adjustable frame side Zbar mounting bracket and a block side bracket without adjustment slots and the "L" shaped curve at the bottom of the bracket facing towards the front of the car. (the assembly manual bracket looks to have slots) Also did 68 ever use the bracket pictured or is this the repop part ?

It is a early production later production change over. Used 67 to later 68. I think it changed from one to another around April 1968 plus or minus.You would have to consult the MPC to get the Ford official transition date for the bracket in your picture. The one you have pictured is the later production 68 up version. The earlier style is slotted for adjustment on the block and the chassis side is fixed with holes instead of slots . The block bracket is also shaped different compared to the pictured version.

I took at look, and for future searches note that we are talking about basic part 7A572, "Bracket Assembly - Clutch Release Equalizer Engine" based on the picture in the first post.
The first two pictures from the 1968 version of the comprehensive 1960-1968 MPC. I don't see any note of a running change here.
The 65-72 MPC circa 1975 lists a revision B of the part, but since the -A from the 1968 MPC is not listed, it should be considered interchangeable.
I suppose that we are discussing a -A vs. -B change, although I don't know that for a fact. However, the evidence sure points in this direction. It is interesting that some revisions will retain the prefix (C7ZZ in this case), while other times they make the change in year (to C8). I've seen both ways and have not come to any suspicions or conclusions, but I digress.
Someone with OSI books could shed some light on when rev A was obsoleted. That will get us closer (considering 1968 vs. 1975), but still not when the change was made at the assembly plant. Sounds like Bob has seen enough of them to provide a plus or minus date, so that is exactly the type of real world feedback needed in a case like this.

Thanks Bob I appreciate the help, the service replacements I have seen are a bright zinc finished was the original natural or P+O ?

John, I looked for a date at the bottom of the assembly manual from the part diagram you posted and its one of the many without a date.
-
Good point. It is interesting that the MPC diagram is dated April 68, with a nod to Mr. Gaines April plus or minus comment.

The assemblyline was bare steel on the brackets and Z bar. It seems that starting in 1970 the assemblyline as well as service brackets and Z bar were both a zinc silver. A lot of things changed for the 1970 model year I am discovering.

I know I have seen a "from" or "after" explanation before in one of the different year MPC's . Sorry I can't remember better.

Here are some pictures to illustrate the difference between the two . Notice the bracket with the round holes has the C7-B part number. The slotted bracket must be the "A" version therefore.

To potentially connect some dots here, take a look at the second drawing, dated Feb 1968.

Early style equalizer bar supports in an original June 13th Dearborn car.

That chassis side fixed mounted bracket pairs with the adjustable engine side bracket in the top picture of reply #11 8.

Yes. Reply #8, that is.
