Input shaft length for 4 spd
The only car I can think of off hand that used a T-89 O/D were 6 cylinder Studebakers!
You want a T-86 O/D.
I did find a T86 without a bell also locally it has a 6.5" input shaft.

1949/64 Passenger Cars used T86's, as did 1953/64 F100's.
1965/67 Passenger Cars used T-85N's as did 1965/72 F100's.
I don't know of any Ford/Mercury/Lincoln/F100 that used a T-89 O/D.
The T-89 O/D is a weak sister of a trans used in 6 Cylinder flathead Studebakers thru 1961, OHV 6 cylinder Studebakers thru 1966.
Gotta be careful of what you buy, because...
T-86 O/D's were also used in 1951/66 Studebaker V8's. 1949/56 6 cylinder Nashes, Hudsons, Kaiser/Frazers, some Studebaker Trucks. 1957 and later AMC's.
T-85N's were used in Packard's, 1956 Studebaker Golden Hawks (Packard V8), 1955/56 Nashes/Hudsons (Packard V8), and some Studebaker Trucks.
Borg Warner T 89 Transmission - Jeepnotes - Off Roading in Style
- T85/89 had a 4th gear added and became T10
- T89 is a big, beefy 3spd used with many early to Mid 1960s engines
- T89 also used by Ford (w/ overdrive) (390) and by Olds mid '60s (394)
- T89 (w/ overdrive) Ford was the last to offer them in '71 pickups
- T85 (basically the same tranny as T89) was also used with Dodge-Plymouth 426 engine in 1964
- T10, T85 and T89 all have the 9 bolt side cover, however the T89 shift arms were staggered as opposed to inline like the T10 and T85
- T89 and T10 bolt patterns look very similar also to 1949 thru 1964 typical Ford bellhousing bolt pattern
- T89 was fitted with a BW overdrive unit on the rear. These didn't bolt to just any tranny, there was an adapter about an inch thick (25-26 mm) that went between the tranny and over-drive unit. The output shaft of the tranny was a short length and splined to fit into the over-drive unit as well
- The T89 also was used with the over-drive in the V8 torque tube cars

And yes, there appears to be more "car" trannies than truck. If I was to come across a T85 I could pretty much confirm it is a truck trans? And they are marked.

Try and find one listing for a T-89 in any of these cars/trucks in a Ford car or truck parts catalog. Happy hunting, cuz there ain't any such thing!
If I was to come across a T85 I could pretty much confirm it is a car/truck trans? And they are marked. AS2-T85N
No Warner T-89's in any Ford Car/Truck.
In addition to the other applications I listed, T85N's were also used in 1949/55 Lincoln's. Hydra-Matic (!) was an option (1950/55).
1965/72 F100's with 240/300/352/360/390's used T-85N's. I have this exact same trans in my 1965 F100....which I bought new, so I know the trans is the original,
I also have the 1941 thru 1966 Studebaker Car & Truck Parts Catalogs, so I know what Studies the T-85, T-86 and T-89's were used in.
And...I also have 1921 thru 1956 Packard Parts Catalogs, so I know which Packard's used T85's.
I also collect Packard's and Studebaker Hawks.
And, before I was a Ford partsman, I was a Studebaker/Packard partsman...I kid you not!
This overdrive discussion seems to always go around and around but never gets resolved. You and I have done it and now it happens again.

I think the problem IS the Ford documentation. And this is why we need your help on this. As far as I know, none of the Ford Manuals I have (including my 66 shop manual I use for my engine) connects the dots between the Ford designations for these transmissions, and the "numerical designations."
For example, in the 56 Shop Manuals and "Illunstrations Catalogue" Ford call the transmissions "light duty 3 speed" or the like. And there is a wonderful picture of the overdrive unit as well. BUT NOWHERE is there a picture of them together - not even in my 49-51 Ford Car Manual. And also NOWHERE, that I can find, is there a designations of what NUMBER (ie T-86, T-89 - just as examples) those "light duty" or "overdrive" transmissions are.
Now you being the complete and undisputed Champion of Parts and Numbers here, and having vehicles with Overdrive transmissions, AND with your experience in other vehicles,
YOU , MR. BILL are probably the most (if not the only person) qualified to tie this info together. If not, then we have to rely on articles and other piecemeal info on these overdrive transmissions that is often just plain contradictory. - The subject comes up quite often, it never gets "nailed down" and we really need your help.
What I would love to see (and you did it partially above) is a short list of 48-57 Ford trucks and what Overdrive Transmission was used in each of them - by BW number (it T-whatever) and If possible, an interchangabiltiy list (like the OD transmission off a 67 F-100 will fit on the bell housing of a 57, etc - just using this and an example). You did it partially above and it answered a lot of questions
Maybe if we could nail down that info, we could all get on the same page about overdrive transmissions....
Can you help us?????????????

Ford and What became Borg-Warner then Tremec formed some of the most un-holey allences in the automobile business and swapped parts and spit as it pleased.

One of my rare and uncharisteristic attempts at being diplomatic.

Well one things for sure about this tread - a lot of mules and a lot of pissin' - seems to always be the way with these overdrive "discussions."

See what I mean?
I guess that Lincoln has a SBC in it.
The distance from the faceplate to the end of the input shaft is: 6"
The other measurements are:
36" from end of the input shaft to the end of the tailshaft.
The numbers on the transmission are:
main case: T85C-1A
tailshaft: WGR11
