Steering shaft dimensions, Please?

[kerrywittig]

I'm away on business for a few months and so when sitting in my hotel I am gathering parts and info to help expedite getting my 1970 S2 back up and roadworthy........

So therefore I ask what may seem strange questions....because I can't just walk up to my car and take a look or get a measurement...

So here goes....What is the diameter and spline count on a 1970 S2 steering shaft at the steering wheel?

Why?  I plan an putting a quick realease on the steering wheel to make entering and exiting a more "open" effort...

Thanks for doing my foot work!!

AFAIK, it's 9/16" 36 spline.

Oops, wrong end.  This site says 5/8" 36 spline for the steering wheel:

PS: interested in hearing more about the QR steering wheel hub you use.

So....has it been determined exactly what the dimensions are for the 1970 S2 Europa steering shaft at the steering wheel?

9/16" or 5/8" w/36 splines??

Also is the steering wheel mount to the hub via 6 or 7 screws?

Again I am away from my car till 11/20.......any insight appreciated.

Trying to come up with a quick release steering wheel hub w/horn operated via OEM wheel and button. Almost there, just tying up the last loose ends..........

At 64 years young and not as "slim" as I once was, this is HUGE.....(pun intended)!!

It's 5/8-36 at the steering wheel end and 9/16-36 at the coupler end.

The stock steering wheel is held on by 7 rivets: two for each arm and one extra at the top.  The problem with trying to fit a QR using stock components is that the stock wheel's spokes are individually attached in recessed slots in the boss.  It could be done but it will require some careful machining.

I went with a Motolita steering wheel, Lotus boss and a QR from Lifeline (through DemonTweaks).  Works great.
