Steering Wheel Fitment 914-Four v. Six, Is there a distinct difference or are they interchangeable? Options

70/71 914-6 Part #'s
914.347.803.10 Hard Rubber Steering Wheel
914.347.806.10 Leather Steering Wheel

72 914-6 Part #
914.347.805.11 Leather Steering Wheel

70/71 914-4 Part #'s
914.347.804.10 Hard Rubber Steering Wheel
914.347.805.10 Leather Steering Wheel
914.347.090.10 Hard Rubber with Porsche Signal Key for USA only
914.347.091.10 Leather Steering Wheel with Porsche Signal Key for USA only

72 and Later 914-4 Part #'s
914.347.804.11 Hard Rubber Stearing Wheel
914.347.805.11 Leather Stearing Wheel
914.347.809.00 Steering Wheel with Foamed Rim

In conclusion, it looks like the 72 914-6 is interchangable with the later cars because it has the ignition switch steering colomn from the later car but the 70 914-6 is a different part number completly!

Sorry but I have had every version of 914/4 & 914/6 steering wheel & all of them fit on an early (pre-'74) 911 column.

I'll repeat again, the number/diameter of splines on all 914/4 & 914/6 - plus '65-'74 911/912 models is the same !


For any of you doubters, try this - take any 91/4 steering wheel, remove the turnsignal cancelling ring (3 screws), remove the large black plastic 'spacer' (4 screws) & then slide the wheel onto your 914/6 steering column ...

The main differences between an early ('70/'71) 914/4 wheel & a later ('72-on) 914/4 wheel is that the latter has a recessed area in the centre where the retaining nut goes whereas on the earlier 914/4 (& 914/6) wheels it's flat.

The main difference between any 914/4 wheel & a 914/6 wheel is that the 4-cylinder version has the plastic 'spacer' on the back & a smaller diameter turnsignal cancelling ring.

This must be why I sold a bunch of 914-4 steering wheels to 911 guys lately. They were all going to have them recovered to the thicker grip and put them in their early 911s.

I did have one guy tell me that only the 914-6 wheel would work in a early 911.

There is a company doing this and modifying the turn ring. They are not cheap!

It looks like we will have to agree to disagree because I have tried it!

The only modification needed on a 914/4 wheel when fitting it to an early 911 is to drill/tap/countersink 2 holes on the rear to allow fitment of the 911 turnsignal cancelling ring.

This modification is not needed for a 914/6 wheel as it already uses the 911 cancelling ring.

All 914 steering wheels - 4 & 6 cylinder versions - have the same number (& diameter) of splines !

I disagree ... (IMG:style_emoticons/default/popcorn[1].gif)

I am going to have to agree with Lightweight on this one. I had just picked up a wheel from pick and pull this week. My thought is that I would use it on my car while I sent another one out to Dallas Custom Steering Wheels for the double leather (Extra thick grip)wrap. This thread had me worried for a minute.



Car is an 1970 original 914/6.

Here is my investigation from this morning:



Note the recess center.





With the hub unscrewed. One minute process.





On the /6



On the /6



The early wheels have the countersink for the 914/6 turn signal cancel ring.



Hope this helps. (IMG:style_emoticons/default/blink.gif)

Not one of those part numbers is from a 70 914-6!

Yet they both fit on my original factory 1970 914-6!!

Please watch the two videos for a definitive answer to this question.

The person in the video is Ed Mayo, who is the PCA tech committee member for the 914 and early 911. He was kind enough to let me video him in his shop while he moves the steering wheel from a factory 914-6 to a 914-4. We didn't go the other way because it involves removing the plastic spacer.

Video 1 is Ed removing the factory wheel from his personal 914-4. From the video you can clearly see the VIN plate and the VIN on the compliance sticker, plus the 4 lug wheels.





Video 2 starts with a picture of the 914-6, showing the VIN number and the compliance sticker. Granted, the steering wheel Ed takes off of this car is not a factory wheel, but putting on an aftermarket wheel doesn't change the steering column splines. It ends with Ed putting the 914- wheel on his 914-4 and turning the steering to show that it actually will turn the road wheels.



All of this was taken with my Android phone. If you need to verify this, you can call or email Ed Mayo. His information is listed in Panorama, and I am listing it here also.

Any critique of the camera man can be sent to me.

No additional rebuttals?

Ahhhh, I was looking for an answer to this burning question and no videos!!!!!

Early 4 wheels and 6 wheels are the same. They just use different parts to cancel the turn signal. Late 4 wheels are the same spline but use a different plastic hub. Spline count on all 4 wheels are the same as well as early 911 wheels. early 4 and 70-71 6 wheels bolt onto a 911. if the model number ends in 10, its early, if it ends in 11, its late. late 4 wheels require a small mod to fit on early 911 but no mod to fit early 914-4.
914-6 uses the same cancel ring as early 911

the cup on the rear of the wheel is dependent on the column the wheel is being installed on. one is thicker than the other.

I recently bought a Dino wheel with a hub adapter from the classifieds that was supposed to fit my '72 914/4, but it does not. It appears that the spline count is different. Stock wheel fits OK, adapter does not fit. Does anyone have the actual spline count of a '72 914/4 steering column, and a good way to accurately count the splines other than being really careful?

Just finished carefully counting splines on my '72 914/4 steering column and counted 40. Counted the splines on my Dino hub adapter and it looks like there are 41. Is it possible that the early 914/4, 914/6, and early 911 have steering columns with a spline count of 41, and the '72 and later 914/4 has a spline count of 40? Hate to beat a dead horse here, but I'm trying to figure out how to mount this new Dino wheel.

I bought an early 4 steering wheel for my Six. I took the plastic ring off the back of the wheel and I bolted it up to my Six with no problem at all. All Scotty will have to do we need install the complete wheel on the car, is drill and counter sink the two holes on the back of the steering wheel. So for whatever that is worth.

This thread should be moved to the classic thread Forum.

The only detail that seems to be excluded here is the Diameter of the wheels in question.
My understanding is ALL 914's are 380mm dia. wheels & that the early 911 wheel is a LARGER dia. ?
And, that is the other reason 911 guys are seeking 914 wheels for swap?

All the 914 wheels and all the early 911 wheels have the same number of splines. They interchange. I guarantee it. - I have all those cars in my shop so I can prove it.
