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

[c12croft]

The caption lines essentially cover it all.
Can the steering wheels of the sixes fit the fours and vice versa?
Specifically, can the wheels shown as advertised for one also fit the other?
Although I've not verified it yet in any tech manual, I've got the sense that the answer is no, just based on reading the tech info found in eBay ads.
Can anyone here confirm my suspicion here or not?
note: extra credit given to those who bother to answer and include a description of the physical differences
Thanks

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.
