Was the 914/6 steering column different than the 914? Was the early 914 different than the late 914?

Yes. Yes. The Cap'n

So, three different steering wheels as well? And they are not interchangeable? I can't put a '76 steering wheel on my '71?

No, Different backplate and canceling ring for the 76. 70-71 wheels are interchangeable. 72-76 are the same.

Thanks guys for confirming my suspicions.

Does anyone make a hub to adapt a Momo wheel to a '71?

You can get an adapter for the MOMO to the Grant hub for the early 914.
Plus you can order through Baxters Auto Parts.

Thanks again... I've seen the Grant adapter, but I'll be damned if I can find a Grant installation kit for anything other than a 914/6.
