[7TPorsh]

Steering lock?

[SirAndy]

Steering lock?

No, the steering lock is at the end of the long shaft.

My 911 switch didn't have that hole, what year/car is your switch from?

Later 911s 1996 - on (maybe earlier not sure) Porsche added a key lock for car with automatic transmissions. It prevents you from removing the key unless the shifter is in Park. The cable from the shifter screws into the ignition lock at that threaded hole.

Makes sense; when I turn the key to the off position, I can see something move at the back of the hole.
Thanks for the info.

The switch is from the 964 model.....

The 964 part number is certainly a big clue.
Never touched one that new.
Would probably work in a 6 conversion. Get the switch and plug that go with it.

It came complete; right now I'm looking at fitment without doing major changes. I studied Sir Andys thread and would like to install the switch without all the other mods he did

I don't think that's possible, at least not with out major fab. Our 914 column's are not set up to take a 911 switch. If it was, the whole 914-6 conversion would be much easier.

You think my best 2nd option is to cut the "arm" off ? NARO did it that way; but I would prefer to not cut it. A non-working lock would
be ok.

And, I contacted the guy you referred me to, Tom Butler, he had the full conversion parts. Still kicking around that path, concerned I could get in over my head.

Jeff Hines had a pretty easy solution Jim. Maybe do a search here with "sixnotfour" as the member and +911 +ignition +switch as the search string.

Thanks; looks very interesting and probably the easiest option so far

[theleschyouknow]

wow did that search work for you?
I tried on the site and via Google and didn't turn anything up

This is all I could find regarding cutting the 911 ignition switch and cuttng off the 914-4 switch.

That's got some good pics, thanks for posting the link. I'm curious whether the complete switch could be mounted but not have a working steering wheel lock; such that the steering column, and turn signal/wipers switches would not have to be changed ??

According to the thread Naro914 cut the locking part of the 911 ignition switch off. He also cutoff the 914 switch and welded up the hole. The 75 has a plastic housing. I don't know if that would help or make it harder to close up. I have a 73 metal housing. I could bring it this Saturday to compare the two.

Tom is a good guy. I've bought a good amount of parts from him.

Great, I'd like to see it; this maybe comeing together.

Thanks all for all the input, it's a big help

I fabbed a small sheet metal box when I did my car.




I made my steering column from a 1973 911 part and welded wings on it to match my 1974 Chassis then plated it.



My steering column locking mechanism as well as all of the switches work as designed.

Really nice professional looking job ! (IMG:style_emoticons/default/smile.gif) Does the steering column use the original shaft ? Are the 911 and 914 shafts splined alike ? If different, what mods are required....

911 & 914 have the same spline. If you are using a 911 steering shaft it would be best to use a wheel from a 70 or 77, 914. No mods required. The later wheels require a small mod and the fit is ok but not perfect because of a chamfered shaft vs flat.
