I sourced these parts at a shop here in Costa Rica. There's a couple of early steering wheels in good shape as well. The wiper is operational. And complete! If some one is interested in these let me know what you'd pay. I could ship directly from here but I don't know the cost. I can also bring them back to the states with me in a few weeks.
Earlier steering wheels have a center button that actuates the horn. Cushioned pad and horn buttons on the spokes would be 75ish and later. Keep on diggin’ up parts Matt
