Custom Hub Adaptor for Steering Wheel

[Gandalf]

Anyone able to make me an aluminum hub adaptor for a custom steering wheel combination?

It is for a C6 (2006-2010) steering column to a std Momo wheel. I have searched high and low and cannot find anyone that has something already made. I have spoken with Sparco & Momo - nothing. They make adaptors up to C5. Phat made a short run for the C6 but no longer have them.

I guess the hardest part is being able to machine the spline for the column shaft to go through. (Broach?) If I can find an existing hub adaptor for a different vehicle that has a smaller shaft, maybe get the hole machined for a larger shaft? Otherwise I can cut the the aluminum hub from the existing/stock wheel and have an adaptor plate machined and somehow attached?

Any guidence appreciated.
Thanks,
G.
