Just as a follow up - I'm still having no luck on finding a bolt-in solution for a combination tilt/telescoping setup, but I've had some success with other suggestions of a custom made "spacer" that would sit between the steering wheel and the original wheel mounting points. If anyone's interested, here are some links to check out, or you can Google "custom steering wheel extension."
