Dear Loren, Jim, Dwaine, Mark, Dan, and mid-60s Buick
"detail oriented types,"Since I settled this problem another way, I won't be able to join in on this but I certainly wish you all the best of luck on this project!
As long as some of you are considering getting a brand new replacement steering wheel, you might start scratching your heads over the problem of restoring the horn bar. It certainly shouldn't be a problem to have these parts sent to be rechromed. So the 64-dollar question is whether or not there is some clever way to repaint the black background.
Restoring both parts of the steering wheel would certainly be very satisfying. After all that is the closest part of the car to you when you drive it!
Good luck! Edouard
