9 inch yoke - different lengths?
I ask as I don't know what my '82 has and my parts and illustration guide simply shows it as a 1330 industry design so I take it is the 1330 ujoint yoke style. It also says its 3 3/16" over all length.
My problem is I am looking at a 31-spline Currie complete center chunk 3.25:1 ring and pinion with the Detroit trutrac. It says it comes with a short 1330 ujoint and on Currie`s website they only show a short and a long 1330 ujoint and I am curious if there are only two styles a short and a long. Seems like based off the 3 3/16" overall length my truck should be a short yoke.
Trying to figure out if I need to plan on having a new driveshaft made up.
Where did you find a source that says the slip yoke is 3 3/16" overall length? It's not the Ford truck parts catalog, that's for damn sure.
The thing is, you need to look up the driveshaft to discover what the code for the slip yoke is.
Once you get the correct code (8' bed #116), you go to the slip yoke charts, cross the code to the part number (#116 = EOTZ-4841-C), then get its specs.
So far, the only thing I know for sure...is the yoke uses a 1330 u-joint.

It's in the parts and illustration guide I already shut computer down but I can get the page number tomorrow though. It's also not the slip yoke it's the u joint flange that bolts on the pinion of the axle. There is a page it states type 2 and it has A thru F or G on a drawing of the 0art with dimensions in the cart below. Only one was shown here.
But I dont need the part. Trying to find out how many different lengths are available. Hate to spend $1700 on a Currie third member only to be caught by surprise that my driveshaft is now too long. Currie lists a short and a long 1330 style yoke but it leaves me with the question on if it's the same length or not.

Look at the 4851 companion flange in the pic:
D9TZ-4851-A .. 9" Rear Axle Companion Flange - Use with 1330 U-joint = 1979/83 F100/150, Bronco & E100/150.
I am sure they could measure both setups if they don't already have it and you could measure yours to see what one would match your truck.

Well, that's impossible and it's not a yoke, it's the companion flange on the rear axle.
So, did the OP measure his flange or go by what some clueless dummkopf said it was?
B) I don't care what the hell it is called. You keep calling it a companion flange when the parts and illustration guide just simply states "Flange Assembly". So if you truly want to split hairs over calling it a yoke then I can split hairs about how you are calling it a companion flange when its listed as a flange assembly.
C) Again as I stated in my original post if people would take the time to read and comprehend what was posted its all in my first post. That 3 3/16" overall length was taken from the parts and illustration guide. Section 48 Page 6, that was the page I looked at that appeared to be right.
But the big thing is nothing you posted is of help to me outside of the measurement. My question was and still is, are there just two sizes of joint or not. Is there a industry standard for the 9" where all short styles are the same or is there numerous different sizes for the short listed ones.

I gave you the part number, said it was the 1330 type, listed its applications, so there was only one type installed on your truck. I posted the parts catalog pic of the 9 inch.
Later I posted another pic that showed the type of flange and that it was 4 1/16" long.
I had to look up the drive shaft to discover that the rear 1330 joint (C3AZ-4635-M) is different than the front 1330 joint (C3AZ-4635-L).
Here's the parts catalog pic that shows the u-joint specs, look for these two part numbers on the right. Enlarge the pic by clicking on it twice.

But that's the thing. I wasn't asking for part numbers for the flange that I have. I was simply asking was there a standardized short/long kind of thing or were there numerous different sized 9" flanges. I have the flange already installed on the truck. I don't need a flange. Im trying to find out about the so called "short" flange on the Currie if its the same as the 1330 flanges used on the 9" that are short.
Im sorry you went to the trouble of looking up part numbers, but honestly no where did I ask for part numbers my simple question was if there is some kind of standardized sizing for these flanges like was done with other areas such as a long water pump vs short water pump or a heavy balancer or light balancer. That was the only thing I am trying to figure out as I doubt Currie will reply to my email as the automatic reply was just stating they would be closed from 12/21/18 to 1/2/19. But if I do get a reply if they give me the over all length of their flange they call as short and it matches what is supposed to be on my truck then I should be golden then.
