I haven't had any issues with the Billboards on either car

I just took off the wheels and tires on the 1965 because I think the billboards were 20+ years old and the wheels were the original Magnesium ones. I kept thinking that every time that I drove the car, that the tires or wheels were going to explode, but they never did
I went with a new set of wheels and Billboards
