If you look at my thread,"One way to total a '32 Roadster" and look at the front axle of that car they are all pretty similar. This car belongs to a fellow club member so I know first hand there were no failures. When the car flipped it's first contact with the ground was the right front wheel and the axle snapped. I don't think this would be a bad product or inferior metal when you consider the weight of a steel '32 roadster several feet off the ground landing on that corner of the car. Just my 2 cents.
