I finally got around to removing the steering wheel just now, and D. Clay is correct: The steering wheel itself IS bent! In all kinds of ways. Now I get to go MTech II or MOMO shopping! I previously pooh-poohed the bent wheel theory.
With the steering wheel off, looking from the spline, and following the shaft components to the firewall, mine still does not look straight. Below the ignition cylinder, there's a 12 to 18" housing with a couple of welds and collars that slants toward the center of the car. Should this be perfectly straight? Below this is (I THINK) the universal joint shaft going either to (or through) the firewall. This shaft angles a few degrees to the right, but I think it's supposed to, correct me if I am wrong.
I'm tempted to get the pros involved at this point, but I want to poke around some more. I enjoy learning about these cars.
