After pulling 3rd member for rebuild,
this is what I found, number 9 not sure what the other piece is for.

Hmmmm
The number 9 or could also be a 6 is most likely an inspector mark, the other part i think is an oil deflector , Fred might have more detailed info on this, is this a 65 or 66 housing.
This is from a 65 fastback - 5F09K
None of the housings that I currently have as bare housings, have that tin piece inside. I have several that have not been taken apart that may have that piece as I have seen it before. Chuck is probably right on the oil deflector.
Could the 9 possibly for the data plate code for a 4:11 rear gear?
-Fred-
The data plate indicates a 3:50 open,
although I don’t believe it’s original to the Kar. It is a June built Dearborn Kar, the pinion support is 5B15 an the third member is 5B2 an I think it’s an Trac Loc Posi. so no way original to the Kar. When machinist was working on engine he thought the Kar was used for drag racing, it had triple valve springs an some other modifications according to him. This may account for the Trac-Loc, but the number 9 in the housing is still a mystery.

Looking at some old posts put up by
Fred, I ran across this housing with an L an the same oil deflector as mine, only differences is this one is an 66 an mine is an 65 with a 9

My October 64 Dearborn K fastback has its original 3:50 rear end and I found the same 9 or 6 inside the housing, but no oil deflector.20190704_115421.jpg
After drawing an 6 an a 9 on a piece of paper, I’ve come to the conclusion it’s definitely an 6, my nine looks totally different than the number on the housing, but my six looks exactly like the number on the housing, Chuck is probably right, inspector number, why some housings have oil deflectors an some don’t is a mystery.

0626211428a.jpg0626211428a.jpgThis is my housing when i was cleaning it up its a 65 mid April Dearborn fastback housing, with the similar 6 or 9 marking, no oil deflector present .
Evidently it’s signifies something at the Dearborn plant, inspector number like you mentioned, sure would like to know for sure.

Im thinking sub assys like complete rear end were assembled at a sub plant and shipped to one of the three mustang assy plants to be installed in the vehicle chassis much like rear leaf springs and complete engine assys.

That other piece is a B9A 4159 A Lubricator for a locking rear axle.

Yes Fred you hit the nail on the head, as any open rear gear i have opened up did not have one , i wonder if they are still available , it would need to be in position before the 3/8 studs were installed.

Based on the picture in the Ford MPC, that piece is held into the housing by two of the studs as they are installed. The piece is no longer available and there are none at any of my parts locaters.

The housing is definitely an 65 style was the oil deflector an option back then, Fred could probably answer that, my opinion is no, it was probably added by a previous owner, like I said earlier the Kar was most likely used for drag strip, you sure wouldn’t want an open rear gear for that. I posted a long article in the old forum about this Kar at the time of purchase, I’ve rebuilt practically everything on this Kar, the third member is hopefully the last thing. A couple of pictures of the rear that came out of Kar, it’s definitely some sort of locker.

The 65 Hipo was not available with a locking rear end. The locking rear end became an option in the 66 model year on a Hipo. The 66 axle housing remained of the 65 style until some time in October of 1965. Therefore that style of housing would have been available with a locking rear end in that time frame of the 66 model year.

According to the repo. door data tag
the Kar had scheduled build date of mid. June 65, were they installing 66 housings with the 65 style then, if so that would explain the oil deflector, but the third member that I posted had a casting date of 5b2 so it’s probably not original to the Kar, I’m confused on this one.

Thanks for that info Fred, i will be looking for one at ford Carlisle this year , im thinking a later year say 67-73 9 inch oil deflector would fit the bill as the housing stud pattern is the same as a 65 ,

The rear diff you have pictured could be an equal lock which was a light duty locking rear diff .
