I’m sure this has come up before. Did a search but couldn’t find the answer. I see elsewhere where they used both the long shaft steering box and the short shaft box in 67.
Is there a certain date give or take that they switched to the short shaft box?
Is the rest of the steering linkage the same other than the pitman arm(larger hole for output shaft on the steering box) for the short shaft box?
The car is a 390 car. Would that designate whether it has the short or long shaft box or just the build date of the car?
Thanks in advance.

That is easy,the big block got the short shaft and the SB the long shaft . The SB also changed over to the short shaft in the later part of 67 production. i don't have the exact date in front of me .

The SB also got a short shaft if it came with a tilt wheel option.

That helps for sure. Other than the pitman arm, is the rest of the steering linkage the same for either box or would the big block effect that at all? Need to figure a few of these things out before I buy anymore stuff I probably don’t need or can’t use.

For a detailed view, at least from a service standpoint, you might consider down loading the 1975 edition of Ford Car Parts, also know as the MPC from here:
http://squarebirds.org/Manuals/1965/1965-72FordPartsTextCatalog/
It's 430mb in size with 45 files.

Your assumption is correct. They are the same.

+1, I agree that ALL big blocks got the short shaft gear box but there is an early AND late version of the short shaft gear box and I would say your build date would get the later one.
Without doing the research again, (you should continue to look for the "when" the change-over took place) I can add to the discussion there were two different short INPUT shaft gear boxes used in '67, identified by the OUTPUT shaft diameters (early & late)... and subsequently, two different pitman arms used. (Early version=small diameter output shaft, Late version= large diameter output shaft). Jim was correct, I believe some clues would most likely be in the MPC to narrow down the date when the change occurred. There is also just as much likelihood the change-over is just an estimated date.

Referencing the 67 MPC on the third post here:
http://www.concoursmustang.com/forum/index.php?topic=10307.msg61286#msg61286
The change over date listed is 5/1/67

That helps a lot. Appreciate all the help on this and other questions I have. I really want to do this right
