Steering Wheel Adapter for a 1968 Barracuda ???
That A-body adapter(Tuff wheel adapter) won't fit a 68 column without a little work. They were designed to fit the 70+ columns. In 1970 the ignition switch was moved from the dash to the column. The columns had to be made larger to fit it inside.
The lower metal ring on the bottom of the adapter will interfere with the 68 column. I've seen some people remove that ring but then you have a large ugly gap between the adapter and the column. Here was my solution...
I kept the lower ring in place but had to sand the inner area so it would clear my 68 column. Then, I machined an aluminum ring that fit's on the base of the adapter. It's tapered so the transition between the small diameter column and the large diameter adapter isn't so abrupt. I saw this done on a Hemi Dart at the Mopar Nats years ago.
