What didn’t Duff’s send me?

I spoke with them about swapping out my stock 68 steering shaft to eliminate the bell shaped joint at the gear box and to get the safer collapsible shaft. This is what I received. I obviously have to maintain the upper portion of the shaft to attach the steering wheel. I only have this one joint and it has the “D” shaped openings. My logic says I need two joints that have a round opening on one end and the D shape on the other. I don’t see how this one could be used at all. My experiences just seem to be unlucky with them.
Am I missing something?

I just did mine on my 72 not too long ago. I think you need a 3/4 DD x 1 DD coupler for the end of the rod at the steering column end by the firewall. You will need another coupling to attach the 3/4 DD shaft to your steering box that has the correct splines for your steering box.
Here is a video that shows how to make the DD on the 3/4 round shaft you have coming from the steering column.

I am not the best at explaining things so I hope this helps.
Good luck!

I should have added that you can get joints that fit the round stock. You can weld them in place, I think the DD option is a little more forgiving, if you need to replace one its a lot easier. You might be able to bolt one of the round ones on the shaft as well but, in my mind a round shaft has a better chance of spinning than a DD style. Just my opinion of course.
Good luck!

So my thinking is correct. The joint they sent me can’t even be used. I guess I’m going shopping somewhere else. I doubt they will take it back without me paying shipping again. I’ll bring it to OCBR to see if I can get most my money back. The guy at Duff’s even confirmed with me how many splines the gear box output shaft had. I haven’t used them for about 10 years and am not persuaded to start now.
Thanks for the feedback.

Sorry to hear that, it sucks when you think you are going to get something done and you can't even get started.
What ends are on the joint they sent to you?

They sent one that has the smaller D opening at one end and the larger D opening at the other. Nothing to go on the splined output shaft and nothing to adapt to the 3/4 round stock piece.

If you grind the round shaft that joint should work for the top. Sounds like they need to send you the 3/4 DD x splined joint and you would be set.

You can't knock duffs without at least giving em the chance to make it right. Sounds like a simple exchange. If their guy sent the wrong part they probably will cover the shipping. Over the years I've had all of the vendors send me a wrong or bad part. It happens.

Yes, I will call them tomorrow to see what they have to say.

The joint sent is correct for attaching the telescoping lower shaft to the cut down upper shaft. You need to cut the long single shaft off about 3" below the steering column. Once you do this, use a bench or angle grinder to grind a flat spot on either side. Just enough so the smaller double D side of the joint will fit snugly on. The larger side of the DD joint will attach to the larger side of the telescoping shaft.

What you're missing is the 3/4" DD to 5/8" (I believe) 16 spline lower joint that goes between the telescoping shaft and the steering box.

Vendors advertise their stuff like it just bolts on. Modifications need to be made on all new parts that supposedly bolt right on.

Am I missing something?

Give me a call at the office (865) 938-6696. The 3/4DD-1DD is for the stock shaft to collapsible shaft connection.

In theory, the other joint would be a 3/4-36 to 3/4DD (most Broncos before Early 1973 were 3/4-36). However, if you did not know if for sure, we would ask that you measure. The spline count is easy enough, but the diameter gets tricky. As Ford used both 3/4-36 and 13/16-36 input shafts on the steering box, it would be easy to come up with the wrong measurement.

In any event, we would be happy to help make sure that you have the correct part. Our goal is to avoid selling and sending you the wrong part to begin with. That is why I have our sales staff ask so many questions, ask for measurements, and sometimes even ask for pictures. There were enough variables from Ford that don't always follow the FSM, let alone the changes (some obvious and some not)from previous owners.

It is not so much an issue about bad luck as it is understanding both what you are trying to accomplish and how to get there. Sometimes, it's an "easiest way to get there" kind of thing; while others, it's a "you can't get there from here" kind of thing. In either direction, we usually have the answer...even though sometimes it's not the answer you hoped to hear.

Give me a call and we will solve your issue.

I do appreciate the comments from Duff's since I haven't been able to call them as of yet. In comment #4 I noted that the spline count was discussed to determine which joint to send. I will be able to call them today. I should be quiet about this part but the philosophy session didn't help my frustration level. I'm sure in the end it will all be good, just delayed.
