You would have to check with Ididit but I'm pretty sure that they use the same spline on the steering shaft that GM has used since the early 50's.
The fun part would be getting the turn signal canceling cam to work and getting the horn to work. That may not be so hard though as they have an adapter for 55/68 wheels
