Change Early 67 sheering shaft

Wondering if there is a product on the market that allows us early 67 sheering sector shaft owners to switch over to a collapsible set up with out replacing the box and all?? I did some searching but couldn't find anything.

I don't think there is. I had to ship my '65 steering box out and I looked into this getting the modular unit for convenience-- no luck. You would have to use a new steering box entirely.

4 speed
Rally-Pac
Bench Seat
Power Steering
All-around discs
Aftermarket A/C

And not nearly enough time

Very simple.
Change all to 68-

Then why do you want to do this?? I'll bet it the scare tactic of the Spear O-Matic paranoia syndrome??

Chock nailed it, perhaps not on the paranoia bit though ;-)

I replaced my early '67 (I think all '67s had the solids, just a mid year change to linkage) with a '68 two-part shaft with bellows on the outer tube long ago. It was a pretty easy swap for me since I was already replacing the wiring. The factory '67 wiring will not immediately adapt a '68 part. That said, while it is a collapsing column in every sense...I was surprised how much force it would take to collapse...presumably before it penetrated a sternum but...DAYUUUM. Then again, if the Spear-O-Matic is a concern, remember, there's no airbag in front of you when in that no-crumple-zone car, but shoulder restraints would be a better concern than a collapsible column.

If budget allows and you're not particularly into the vintage look, companies like Flaming River (I'm sure there are others) offer all sorts of modern convenience and safety.

Good point, when I did my swap it was not only part of a re-wire but also a swap to a TCP R&P.

In 67 the 390 cars did have the 2 piece or short shafts. Only ones from the factory at that time.
My 67 390 GT car has short shaft. SMB-E

I had this conversation when I first bought my 66. After looking at all the options, I decided that 3-point seat belts were the best remedy. However, I would still like to do something about the shaft at some point. I have plans on doing EPAS upgrade down the line, and that should help a lot.

Has anybody ever done any research to find out how many people were killed in Mustang crashes where their death was attributed to the non-collapsible column? I bet the number is amazingly low. Probably about the same number of people who were killed by a ruptured, flaming Mustang gas tank in a rear end collision.

Good point. If the numbers were available it would probably be about the same as dead by a Meteor--or something as that.

It's the SPEARED thing that gets me.
Collapsible, non collapsible , padded, not padded deaths are probably near in numbers.
SPEARED , we go back to Meteors, crashes with UFO, elephants, etc. numbers comparisons.

Thank you for the input gents! Obviously new to the classic car scene and everything i watched and read would talk about being impaled by the shaft in a front end collision. Wasn't a pretty thought, so wondered if there was anything out there to remedy it, however it sounds like its more of an old wifes tale than a common occurrence.

About 30 years ago my Dad got hit head on by a bulk cement tanker while driving his 66 ranchero. The semi pushed his car several hundred feet in the opposite direction. He was not wearing a seat belt (doubt the car had them) his torso hit the steering wheel so hard that the small chrome steering wheel appeared to be on backwards. It did not spear him.

A 3-point seat belt pretty much eliminates the need for the collapsible column, except in cases where the left-front is crushed rearward so badly the column moves into the passenger compartment, pinning the driver to the roof. I once parted out a 65 K code where this actually happened. He survived, by the way.

As for the flaming gas tank, I once tabulated stats showing more Americans have been killed by shark bite than Mustang gas tanks.

Amateur restorer. Well, sometimes I have been paid for it. But not right now.

Here's the thing. GM used a "front steer" suspension which means all the junk is up front. The steering box with it's solid shaft was just behind the front bumper. In a accident it would get shoved into you. Ford used a "rear steer" system. Everything is BEHIND the suspension. The steering box is just behind the fire wall. By the time that shaft gets stuffed into you, that's the least of your problems! I have no issues with my Spear-O-Matic.
