Is the steering coupler really necessary?

['74 Sport]

Go here: Borgeson

It will be the one listed for "Chrysler" (5/8"-36 spline x 3/4" smooth).

I used the flaming river piece as I had the exact same clearance problem.
Had ordered a Borgeson piece I hoped it would work as it was much less expensive than the F/R one but the splined end didn't fit on my steering box even though the dimensions given were exactly the same as flaming rivers?

I suspect it might not have been the splined end specific to Chrysler. When I spoke to a salesperson, they were sure to point that out to me - something about the shape, not number, of splines.

Yea now that I see they have a chrysler specific u-joint .
I wish I would have known that ahead of time coulda saved Myself some $$$:banghead:

The solid joints may work with manual steering, but with power steering, the input shaft moves in and out, and that movement is what shifts the shuttle valve in the valve body to direct fluid to one side of the power piston or the other. The factory joint is filled with grease and designed to allow this in and out movement. Have someone wiggle the steering wheel back and forth a little bit while you look at the steering box and you'll see what I mean. If you're going to headers, you may want to think about going to manual steering too.

74 Sport - do you have any pictures of the installed coupler? How about external diameter and length? (I've looked on the Borgesen website but it won't display the detailed info page.

Bogie - what Neon should I look for?

Are all manual steering boxes 5/8 36 spline? I'm sure the diameter of the shaft on my steering box was 3/4

Finally, how does the stock coupler come off?

Thanks

...but with power steering, the input shaft moves in and out.

Now you tell me. Where were you when I first raised this issue?

The new coupler is welded onto the steering shaft and a hole has been drilled into the gearbox input shaft for the set screw. Other than that, I don't have a problem reversing my decision on how to handle the clearance issue.

Any idea how much in/out movement is generated with a stop-to-stop turn of the steering wheel? The column is not in the car right now, but I guess that will be the next thing I need to do, so I can figure out what to do now.

Thanks for the heads-up,
Jerry

Sorry guys I forgot he manual / power difference I know the front wheel drive joints work on the power truck boxes.

There's about 1/8" total in and out movement as I remember.

Final assembly... no problems.
Aaron and I finally installed the steering column with the Borgeson coupler I discussed a while ago. The set screw is locked down into a shallow hole I drilled into the splined input shaft, and the smooth end is welded securely onto the steering shaft.

In the second pic you can see how close the shaft gets to the header tube. By the way, turning the steering wheel stop to stop, there is absolutely no movement of the input shaft in or out of the power steering gear box - all it does is rotate. Whew!!! I was worried about that for a while, since we welded the coupler on solid.

The whole column swap to have a floor shifter was a big ordeal, so I'm glad to be done with this.

shoot me the part number for the Flaming River and I will see what I can you one for.

Does this mean you have an "in" at Flaming River? I have the problem fixed for this round, but I might want to consider something else for future projects.
